Encompass Hires Digital Marketing Director to Enhance and Expand Ecommerce Sales and SEM

Lawrenceville, Ga., April 30, 2019Encompass Supply Chain Solutions, Inc., a leading provider of Distribution, 3PL and 4PL solutions for a diverse range of finished goods and repair parts, today announced that Jayne Sutherst will join its IT team in the newly-established role of Digital Marketing Director.

In this position, Sutherst will be responsible for managing all aspects of Encompass’ digital presence, primarily its main ecommerce site encompass.com, client web portals, search engine optimization and online and social marketing.  She is tasked with enhancing the online experience and customer support for both B2B and B2C users.  Sutherst will be based at Encompass’ recently-opened distribution and administrative facility near Fort Lauderdale, Fla.

Sutherst joins Encompass from MAPEI – a worldwide producer of adhesives, thinsets and sealants for buildings – where she served as digital marketing manager. Among her many accomplishments, she led the redesign and strategic planning of MAPEI’s flooring installation product website, which drove 1 million unique visitors to the site within eight months of launch.

Sutherst has 15 years of experience in web development, ecommerce and online marketing for both B2B and B2C audiences. She has worked in corporate retail and agency environments, beginning her career with American Express as a multi-media instructional designer manager.  Sutherst earned an MBA in Marketing and undergraduate degree in International Business from Nova Southeastern University.

“With her extensive background in web design and product sales, we are confident Jayne is the perfect fit to lead and strengthen our ecommerce initiatives,” said Encompass President and CEO Robert Coolidge.

He said Encompass’ tremendous growth in the Home Appliance space, along with the company’s spike in hosting co-branded manufacturer consumer ecommerce solutions, necessitated additional support within its technology department.  Plus, since Encompass offers one-on-one call center service and counter sales at its facilities, it needed to ensure consistency across all customer touchpoints, said Coolidge.

“It’s critical for us to deliver online resources for service dealers, distributors, manufacturers and consumers that align with our call in and walk in experiences.”

Coolidge said Encompass in past years mostly only served repair servicers, warranty companies, retailers and other businesses involved in aftersales product support.

“Through manufacturer partnerships and our own marketing efforts, we are serving more consumers – some who have used service professionals and some ‘do-it-yourselfers’ who prefer making repairs themselves. They have found that we often have complex parts they can’t get from traditional ecommerce sites.”

Coolidge also said that while Encompass maintains counters/will call at each of its distribution facilities in Georgia, Florida and Nevada, electronic ordering accounts for a growing portion of company sales.

“Ecommerce continues to complement our increasing brick and mortar presence in the U.S.,” he said. “With strategic locations, we can offer next or two-day ground shipping to most of the country, which typically meets the needs of both our business and consumer customers who prefer delivery service.”

Accessing and Testing Microwave Door Switches

**NOTICE**
Due to the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

WARNING : Disconnect the microwave from any power source before moving forward.

Microwaves include three switches located behind the control panel: primary, secondary and monitor switch all actuate to keep the microwave from cooking the kitchen while the door is open.

Accessing the Switches

  • Remove the two Phillips screws that hold grill in place on top of microwave. Remove grill and lay aside.
  • Locate and remove the one Phillips screw that holds the control panel in place.
  • Lift up control panel and gently pull toward you. This will provide access to the three switches.
  • Remove all wires from control board. All wires are different from each other and will only fit on the terminal they were designed for.
  • Use needle nose pliers to remove connectors from terminals that can’t be removed by hand. Gently squeeze  connector to release it from the terminal.
  • The last wire to remove is the ground wire, which is connected to the microwave frame. Set control panel aside.
  • Remove  access cover and set aside.

How To Test the Switches

  • Set the multimeter to OHMS to test the three switches.
  • Please note that the primary and secondary switches are tested with the door open. With the door open, place the multimeter leads on the connectors on the primary switch first. When closing the door, the multimeter should produce a beep if the switch is good.
  • Test the secondary switch in the same manner.
  • Test the monitor switch with the door closed. When opening the door, the meter should beep.
  • If appropriate beeps did not sound on any or all three of these switches, replace the switch.

These three switches serve mainly to keep the microwave from operating with the door open. The switches also deliver voltage to the diode and magnetron which heat the microwave. If the switches test positive, this further confirms that magnetron has failed and needs to be replaced.

It’s time to button up the microwave. For most people, this is as far as you may wish to proceed. There is an ever increased chance of suffering a powerful electrical shock from the high voltage capacitor, which retains a residual amount of electricity. It will need to be discharged before the magnetron and high powered diode can be accessed and replaced.

Route the control panel wires back through the appropriate slots in the access cover and reattach the cover to the microwave frame. Reconnect the ground wire first and then reconnect all other wires to their compatible terminals.

Push the control panel back in place and secure with its Phillips screw. With the door open, replace grill cover. Opening the door makes it easier to replace the grill. Secure with its two Phillips screws. Do not over tighten these screws as the grill is made of plastic and it could break or crack.

How to Replace Whirlpool Refrigerator Water Tank and Filter Head Assembly

**NOTICE**
Due to the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

When a leak occurs inside a Whirlpool refrigerator, the water tank and filter head assembly could be at fault. This is the part that connects the water supply line behind the refrigerator to the filter and then to the inlet valve. In an area with hard water, buildup can clog or crack through the tubing. Following are steps to replacing the assembly with part #WP12956202.

1. Unplug refrigerator and turn off water supply
Always be sure to unplug an appliance before starting a repair. Also, because this repair involves replacing part of the water system, turn off the water supply at the local shut-off valve behind the refrigerator. The part being replaced connects directly to the supply line, so disconnect the supply line from the water inlet valve at the base of the refrigerator while you’re behind the appliance.

2. Dismantle refrigerator interior
As the assembly is mostly positioned inside the refrigerator, dismantle some of the inner paneling. To get started, open the doors and remove the right side shelving. (Just pull up to remove the
hooks from the rear brackets and slide them out.)

Next, locate the water filter cover at the top of the refrigerator. Press down the tab to open the covers. Turn the filter counterclockwise and fully remove it. Press the back of the cover panel free of the hinge pin, pull out the whole cover panel and set aside.

Remove the interior access panel in the middle of the right back paneling inside the refrigerator. (This is the panel with the four small holes around the perimeter.) To remove it, insert a flathead screwdriver into each of the holes to depress the locking tabs. For the top two holes, press in toward the opposite hole. For the two lower holes, press the screwdriver down to disengage the tabs. Tilt the panel down and wiggle the bottom free from its mounting tabs and set the panel aside.

Then, remove the upper access panel by inserting the screwdriver into the central hole along the bottom and disengaging the locking tab by pushing it up. Pull the panel out and set aside. The water tank at the back of the refrigerator’s interior is now accessible, as well as the filter head running up the back into the ceiling.

3. Remove old water tank and filter head
The water tank may still contain water. Before removing the old parts, place a towel at the bottom of the refrigerator to catch any leaks.

First, loosen the housing that holds the filter head at the ceiling. Do this by prying open the mounting tabs toward the front of the housing and then rocking the back of the housing free until the housing is supported only by the lines running up to the filter head.

Next, press down the tabs at the top of the blue water inlet valve so you can pull the small tube free from the top. Once it’s free, you can remove the transparent support housing around the tube. Also, pull the water line to the left out of the mounting tabs. Completely separate the housing bracket from around the filter head and set  aside.

Move to the rear of the refrigerator and locate the water inlet tube that was disconnected at the start of the repair. Loosen the screw that holds the tube in place. Push it down and remove the plastic retaining clip from around the tube. Then, remove all the screws holding the lower rear access panel in place. Set the panel aside.

Return to the front of the refrigerator. Start removing the columns of the water tank from the retainer clips. Once they’re all down, carefully pull the water inlet tube into the body of the refrigerator.

4. Install new water tank and filter head
Push inlet tube into the hole at the bottom of the refrigerator. Feed as much of the length through the hole as possible. Next, align the new water tank in the back of the refrigerator so the inlet tube is to the right.

Press the columns of the water tank into the retaining clips until they click and engage. This may have to be done one column at a time to make sure everything fits properly. Return to the rear of the refrigerator. Remove  protective cover at the end of the new inlet tube. Place the old plastic retainer clip on the new tube.

Reattach the rear access panel. Slip the water inlet tube through the bottom cutout and the power cord through the top cutout so nothing gets pinched. Then secure the panel with the screws around the perimeter. Next, attach the water inlet’s retaining clip to the middle of the panel and connect the inlet tube to the water supply line.

Return to the front of the refrigerator. Now install the new filter head attached to the water tank. Take the transport tube support from the old assembly and attach it to the filter head’s inlet tube. Also, attach the filter
housing to the filter head. It should snap into place around the arms at the top of the filter head.

Next, reattach the water tube to the inlet valve. Pry the blue valve slightly forward to make more room. Then, push the tube firmly into the valve. It should go all the way in until reaching the wider portion of the tube. Push  valve back into place.

Fit the longer water line into the groove along the left side of the cavity. Once the tubes are in place, attach the new filter head to the top of the refrigerator. Line up the back of the filter head assembly into the rear of the cavity and then press the cylindrical housing into place. All of the locking tabs should be heard to engage.

5. Reassemble the refrigerator interior.
Start by reattaching the upper inner access panel. Hook the top of the panel over the arms near the filter head assembly. Then, swing the panel until it is flush with the back of the refrigerator. Press firmly into place.

Next, install the lower cover. Slip the bottom of the panel into the groove, and then press the rest of the panel flush with the back of the refrigerator until the locking tabs engage.

Then, install the water filter housing cover: there is a hinge pin on either side of the filter head housing. Slide the matching hole of the hinge at the back of the water filter cover over one arm. Then slightly stretch the other side of the cover to reach around and grab the hinge arm on the other side. Take care not to crack the plastic. Before reattaching the water filter, twist and remove the bypass cap inside the filter head. Twist the water filter into the new filter head clockwise. Then, snap the water filter cover shut. Reinstall the shelves, shut the doors, and
plug in the refrigerator. Be sure to also turn back on the water supply.
