MER5520AAQ Maytag Range - Instructions

unplugged oven. removed 2 screws that hold the sensor in place, then removed the dozen or so screws that hold on the rear panel, unplugged sensor and fed wire through insulation. identified and installed correct harness adapter then fed new wire and connecter through insulation and connected to adapter. installed sensor retaining screws.plugged oven back in and tested function.no dice. unplugged oven once again. removed oven control panel and upon inspection of printed circuit board discovered 3 solder joints had failed. dang. resoldered failed joints and also sweetened up a few others that looked suspect. reinstalled controller, replaced all retaining hardware, and plugged in the oven. tah-dah!! works like a charm now. moral of the story is check the pc board first and save $50 for unneeded pats!!! or buy the controller from parts direct for $260ish. btw a roll of solder and soldering iron from an auto parts store cost around $10, learned to solder on you-tube $0. amazing all the home appliances yo can fix if you're not afraid to take a few screws out and poke around a bit. CHEERS!

Power turned off. Door of the oven lifted off. Four screws removed, old element pulled out to reveal electrical connectors. Wires easily removed, and element discarded. New element connected to the two conductors, four screws installed and the job was completed.
Very easy. Took about 10 minutes.

When ordering the replacement part, read the posts on how to replace the bake element. Just follwed their lead. The only difficulty is getting a hold of the wire at the back of the range that the bake element plugs into. There wasen't much play in the wire.
PS Be sure and remove the range door or have very long arms.

Moved the stove, unplugged it. took the back off, took out old board installed the new one. It was just that easy and saved us from buying a new stove.

Disconnected power to the range, Took off the oven door removed two screws and disconnected the two electrical connections to the heating element. Made the two connections to the new element and replace the two holding screws. Replace the oven door and plugged in the power cord. Turned on the oven to test and was finished.

1. Shut the breaker off; Jenn-Air's design will have you working around hot leads if you don't.
2. Raise the control panel
3. Remove burner and unscrew the burner connector; trace the wires back to the control panel bottom and remove them
4. On the replacement connector, add the electrical for the control panel. These are not included and can be found at any hardware store; they are a standard size.
5. Connect the new wires and put everything back together.
6. Reset the break and test.

The sensor is mounted in the top right side of the oven.An extra long screw driver helps to avoid damage to the sensor when replacing it.The connectors were the opposite to the old sensor and I did not see that there were adapter cables included. It might help to connect or tie these together as I only expected the sensor and did not look for adapters.I had cut the wires and used wire nuts when I found the adapters.The repairs works fine.

Oven sensor replacement was easy. Thermistor was installed in less than 15 minutes. After installation STILL had "F3" error message. Harness was ok, "Clock" or ECU needed to be replaced. "Computer" is obsolete, no spares available, some companies will rebuilt for $400+. Since the stove was going to the landfill I had nothing to lose by taking the "Clock" apart. It has one chip that is probably the power supply and control chip, another chip is an EEPROM with 128 bytes of storage and the last is a darlington chip that controls the relays. Cleaned up everything that looked like it needed cleaning with alcohol. When I reassembled the unit the pins for the thermistor harness felt loose, so I took it apart, again, and found cold solder joints on all four pins. It must have been there all along but plugging and unplugging the harness finally broke out the solder so I could see it. Soldered the pins back in and now it all works. It's worth a try if you're getting the "F3" message. If the relays on your stove aren't working it would be a good idea to replace the darlington chip. Good luck.

Removed the two screws holding the sensor to the rear oven wall. pulled out sensor wire. It was caught on other wires behind the oven. removed the three screws holding the 8" inspection plate in the center of the rear panel. Carefully move the insulation and reach in to grasp the back end of the sensor wire. Once free from the snag it easily pulls out with the sensor just as stated in the video. using the appropriate adaptor it was easy to re-asseble and and attach to the oven wall. Replace the rear panel with the three screws and it was done

Turned oven circuit breaker off. Removed oven racks. Removed 2 screws from old element. Pulled element out slightly disconnected wires on each end and reattached to new element. Pushed back in and reinstalled the 2 screws, reinstalled oven racks and turned circuit breaker back on. All done in about 20 minutes.

I reoved old drip pans and installed new ones. Very easy, they look great!

I unplugged the cord to the stove. Then I removed the two screws on the broken heating element. Once the screws were removed, I slid off the two wires attached to the element prones. Grab the new element and attached the two wires. Reinstalled screws. Plugged in the cord, and turned on oven. Heating element came on.

I switched the oven sensor easily enough, but it did not remedy the problem, so we are in the process of replacing the oven since it's about 20 yrs. old.

super easy after watching the how to video you had on it and iam the wife not the husband it was so easy thanks

First I called a repairman and left a message. That was 3 weeks ago. So, I 'googled' the error message and determined what part I thought I needed. Ordered the part on Wednesday evening and it was there when I got home from work on Friday. I unpacked the part, got a phillips screwdriver and then watched the repair video on your website. About 20 minutes later I pushed my stove back in place and the flashing said 'set time'. Then I checked both ovens, and have since used both, and everything works!!
