20 Most Recent Kenmore 80809 Microwave Oven Questions & Answers

I have Kenmore microwave model 721.61820100.
It has an "Option" button. Press it. The display say "NUMBER"
Then press "1". The display should say "SOUND" and then "OFF".
Press "Start" and that beast turns silent, well not really, but the beeps are goooone.

If for some reason you don't like it this way repeat the sequence and the sound this time will turn "ON".

The cause of the TE error for us was grease/gunk on some exposed pins and flex connectors (communication bus between controller and keypad) that was interfering with communication with the keypad. Resolution to TE error: Remove the keypad / control board from the microwave. There are three screws on the bottom at the front to remove. Once those are removed, the keypad is held on by clips. Slide the entire keypad to the left and it will come loose. After it is loose, carefully remove all the wired connectors to the microwave. Lay the keypad face down on the counter and look at the control board. The control board is actually seperate from the keypad and connected via two thin flex strips with many small contacts (like a nintendo game connector) . Our flex strips were covered in grease from the hood fan operation. Carefully clean the strip and the connector (with a felt pen if you have one) and resassemble. This resolved the issue for us.

Check/replace the fan. Quickly ! If the micro wave generator is not properly cooled down, it will burn out - very expensive replacement !

The main displays are not fused, sorry, Also the display itself is not wired to the baord. It is either soldered on or has a conductive rubber pad under it to bring power to the crystal. Get your model number and either call sears or another parts company for a price and availability on the main circuit board.

Check the door switches if one is bad it may think the door is being opened and stop the unit from running. If it is from a bad connection it will get worse as it gets hotter while running.

I've got a Honda Civic hybrid with the same noisy beeper. I can't have the parking lights on and the door open. I can't leave the key in the switch while making a phone call etc. I think we have to presume that like the Honda, there is no software controlled override on you microwave beeper... they know best and want you to feel safe and secure that no burglar will be able to make a cup-o-soup in your kitchen without waking you. A few screws and you should be able to expose the main circuit board and apply a layer of bubble gum or silicone caulk or JB Weld to the beeping device. Most have a small hole in a black plastic cylinder... so cover the hole and then test for loudness. For absolute silence, desolder the device from the circuit board and replace with a resistor matching the amount you measure across the beeper contacts with an ohm meter.

Shorted keyboard. You will need to replace the control console/keypad asembly. If you need further help, reach me via phone at https://www.6ya.com/expert/ronald_e6b9572cebe3ad27

Found 2 possible solutions on the net. (1) Check the engineering change at a Sears store. They reengineered the glass tray and the narrow plastic band the tray glides on. Get the new items from Sears. (2) Cut 1/4" out of the narrow plastic band the glass tray glides on. Possible solutions that look promising.
