Funny, The theme song from the Jefferson's is my cell phone ringtone. I loved that show.
Sherman Hemsley, Isabel Sanford and Roxie Roker, rest in peace.
Both Isabel Sanford and Sherman Hemsley both were from Harlem, New York and they both grew up in poverty. I don't think they ever forgot where they came from. Every chance they could, they would donate their money to charities.
Part number of the board you ordered? Did you double check all your wiring connections? It is very easy to miss a few pins on the connectors and very easy to not have the touchpad ribbon connected to the control board all the way.
The switch is all electronic, no way to adjust it. A new switch should solve your problem. NOTE: These switches have failed prematurely because the drain hose is too far in the drain standpipe because the installer did not use the "gooseneck" that came in the install kit, instead the drain hose was just "shoved" down the standpipe as far as it would go.
The So called Sears technician needs to be knocked on the head with a wooden spoon.
This unit was built by LG. THe tech should have called "STAC" (Sears Technical Assistance Center) to see if there are any service bulletins on this problem.
Check for good door seals and that the doors close tightly. Check that the evaporator fan in the freezer runs okay. Remove the evaporator cover in the freezer and check the evaporator and see if the frost is in one spot or on the whole evaporator.
He will now need an electronic control board. Those are high intensity light bulbs the unit uses, and if you install the new bulbs while the touchpad is in the "ON" position, you will blow the board. The unit needs to be unplugged while replacing the bulbs.
Add your service call, your parts mark up and your labor to the price of this board and you pretty much have the cost of a whole new microwave oven.
I saw one house that had a gas cooktop installed with flexible gas connector for commercial use all the way to the main gas valve out side the house. The hose was fastened to the ceiling of the garage and where it went near the garage door when it was in the up position it kept getting crimped. I told the customer he needed to get a licensed pipefitter to install iron gas pipe from the gas main to the cooktop.
