MER6772BAS Maytag Range - Instructions

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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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.

I did not mark wires with their associated numbered connections on the old burner but I did take pictures prior to removing the old burner. This slightly complicated finding the right connections for the wires on the new burner but the photos taken were invaluable in doing so. The placement of burner connections between new and old was different. Additionally, there were 2 connections on new and old that were not numbered. These turned out to be the power to the inner and outer coils and their connections were determined by examining the burners and connecting accordingly. Also, not mentioned in the instructions was a light on the new burner that the old burner did not have. I removed the light and the wire connecting it to the burner and connected the freed new burner connector based on the old/new burner connection numbering. Despite my lack of confidence that I correctly installed the burner, it worked on the first try and I am very happy to have it fully functional again.

oven had to completely come out cause two sheet metal side panels had to be removed to get to hinge.

Two Screws on the back. Pull out heating element and remove wires. Install new wires and replace screws. Done in 5 minutes

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.

Remove 6 screws fastening element to top of oven. Remove most of the screws from the back and pull away from oven. Use pliers and pull wires off of element connectors.Remove 2 screws fastening element to rear of oven. Install new element with fastening screws. Re-Install wires and fasten back of oven. Re-install the six screws to fasten element to top of oven.

Spoke to your very helpful staff, who advised me that a likely problem was the oven sensor. I took a chance and ordered the part, which came promptly. Your service video for the part was most helpful in my decision to try the part. Installation was a breeze, but it was the oven controller board that had failed and not the oven sensor. That called for a service professional, who ultimately fixed the problem. Your service though, was excellent and I would highly recommend you to others.

Pulled oven out unplugged the unit unplugged broiler unscrewed broiler from inside repeated the process backwards turned oven back on

Removed front panel of range, removed switch (2 screws), unclipped wires from back of existing switch. Installed new switch - reverse order of above.

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!!

IMPORTANT NOTE: This element is shaped like a B. The straight line part of the B, which is closest to the back part of the oven, doesn't light up. At first I thought it was a defective part. My husband is the cook and I never realized this. This fact isn't indicated in the instruction booklet which came with the oven. My sister has the same oven and she didn't realize it doesn't light up either. I looked up installation instructions on You Tube and although I was very nervous, it was easy to install. It's a little awkward because the wires are in the back of the oven so have a flashlight handy.

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.

The replacement unit was a substitute part. Wiring slightly different. Instructions bare minimum. Follow instructions and it does work. No instructions as to how to remove the stove top. Been there before so sort of knew how. Nothing in the Jenn Air manual for stove top removal. The control panel has to be removed, two screws on each side and four hex screws on bottom, this allows for the disconnect of wiring for the top.
Remove the two trim pieces one on each side. One screw at top and one at bottom. The trim piece will move towards the rear and come off. Two screws on each side and two in the back will release the top. Remove top and lay on padded surface. You are ready to replace unit.
