Maytag CHE9800BCB slide-in range oven was working fine, no complaints at all, and wife decided to use the self-cleaning mode. A couple hours after the self cleaning mode finished, the oven control panel would not work. No lights, no controls. Stove top knobs work, stove tops all work. Just no control panel and oven will not work. Instead of buying a new $1,500 slide-in electric range, I'd like to buy the relay board and replace. Before I purchase the relay board, any thoughts or past problems with anything else that could be the problem. This is just a plug-in type relay board, I'm assuming, I didn't see anything about soldering any joints or anything.
Answer Hello HungryJoe. You need to check and see if the thermostat 7403P307-60 on the back of the unit is bad. If so, it will cause the issue your having. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html The thermostat has been permanently discontinued by the manufacturer and we don't know of any source or replacement for the part.
What color wire goes where?
The Purple wire will got to the terminal marked BR, the black wire will go to the terminal L1B, the yellow wire from bake will go to terminal BA, the second yellow will go to Fan, The White wire to N, The double black will go to L1 and the green to ground.
My range threw an F code and buzzed then the oven element came on all by itself and went to the maximum temperature. I turned off the breaker but if turned back on, the oven element comes on automatically. Everything else is working fine. Would this be a short in the board.
Answer Hello Garry,
This will be a stuck relay on the control board. You will need to verify the model number on the units' I.D. tag for us to be able to acquire the correct part number for the control for your unit. You can re-post with the correct model number or give us a call at 1-877-477-7278. Thank you for your patience and understanding in this matter.
is the relay board the part I need to make my oven work? my clock and temp. doesn't work either but my burners work.
Answer Diana, Yes, the relay board 74001870 could be, and probably is the issue. That would be the component to start with. It transforms and supplies the low AC and DC voltages to the ERC/Clock, to illuminate the display and operate the circuits in the Clock / ERC to operate the relays and apply power to the elements to heat.
If my Maytag range and oven quit working, except for the light in the oven, is it the relay control board that needs to be replaced.
It tried several times to come back on, but is blacked out now.
Answer Lori, You'll need to make sure you have 240 VAC at the outlet and at the terminal block on the back of the range. Flip the breakers at the breaker box for the range off and on several times. If you have the voltage at the terminal block of the range, you'll need to raise the cooktop and check the Relay board 7428P009-60 for damaged or shorted relays and wires.
