MER8770WW0 Maytag Range - Instructions

So, the F9 error indicates a electrical power issue. First I pulled the oven out and verified I had 240 volts at my outlet.

Then I removed the fire panel over the terminal block and the issue was apparent. The nuts on the terminal block were corroded. This had cause the resistance in the connection to raise and burn up the wire to my oven plug at the terminal block.

I removed the whole back panel and everything else seemed OK visually.

1. I go new connectors for the oven plug, stripped the wires, and crimped on the new connectors.

2. The terminal block DOES NOT come with the nuts to connect the wire to the terminal block. Mine were so corroded they had to be replaced. So I went and purchased the correct ones and installed the terminal block and reconnected all the wires.

3. I applied some dielectric grease to the connections through out the process of reinstalling to prevent it from happening in the future.

Repair of oven sensor easy to install; however, product did not resolve the problem. Returned new sensor and awaiting refund (2 weeks passed so far).

Took the old levelling leg out and screw the new one in.

Remove the door, remove screws from all sides

Remove sides and face of oven door by sliding down from under the oven handle trim.

Remove screws on 2nd light of glass and set aside.

Now you are at the inner door panes. their should be two in an insulated type unit.

Remove the remaining screws from the handle pracket and the permiter frame for the glass/insulation. Remove permiter frame and set aside.

Pull out inner door glass frame. get a pair of pliers and bend tab on frame up so you can pull the frame sightly apart, replace the glass, secure frame tightly around glass slide tab back into reciever slot and bend down ( you may need another person to assist in keeping both lights in the frame while trying to ben tab back in to place)

reassemble door as it came apart carefull not to over tighten the screws, they strip easy.

pulled the old gasket, the new one fitted perfectly. No effort at all.
An instruction sheet would be a bonus. I wish you put instruction sheet in all parts OR a web link for video instructions. a web link would be great

It was really easy, just lift the door off from the range, I set it down on the box that the hinges came in, took the six screws out to release the front fascia of the door from the back, hinges are right there, un-screw and install the new hinges, put everything back together in reverse and lift the door back on to the range, less than 10 minutes!

I watched the video you provide and it answered all my questions. You estimate repair at 10 minutes. My wife said I waz done in under 10 minutes Watch the video, it explained every step and all the little tricks to the snap connections.

1993 model oven, built in wall model, so didn't to remove oven for the normal rear access to replace the lamp socket. As someone else posted, replacement can be done from inside the oven -- BUT the socket removal was more complex than just 'twisting it out.' But below worked! (1) Turned off oven power at circuit breaker panel. To facilitate working in the oven compartment, removed oven door (2 screws on back of door), raised the over door almost closed, put 2 large nails through the hinge holes when they lined up. Lifted the door out (heavy ~20-25 lbs) and put aside. (2) Put work light inside oven. (3) unscrew glass socket lens and the bulb). (3) Using inspection mirror, studied the inside of the socket to determine that its lock tab type and locations -> were on left and right sides of the socket. These tabs needed to be bent in, but they were each held out by a small circumferential length of think metal, a tab about 3/16" x 3/8". These small tabs could be moved/positioned by just finger friction, with a little start with a screwdriver tip on their edge! I got an end positioned to put sharp screwdriver under that end, then pried it (bent it) inward a short distance. Enough to use needle-nosed pliers to pull it completely out - came fairly easily. Repeated on other side of socket. (4) Then, with pliers, bent each of the 4 locking tabs inward a short distance, Used sharp tool to get one socket edge lifted a small amount; then use mini-pry bar and screwdriver to gently pry around the socket in steps, working evenly around its edge. At about 3/8", it was free. Lifted it inward gently so as not to damage the insulation of the 2 wires attached to its rear. Noted the direction of the wire tabs was straight up (keep same orientation on new socket). (5) Needle-nosed pliers on each connector to gently work the connectors off their socket tabs. Note one tab is larger than the other. Keep the wires inside the oven compartment. Don't damage the insulation. (6) Pushed the wire connectors onto their respective new socket tabs. Aligned socket with the tabs upward, and inserted it, careful to nurse the wires back into the oven wall hole; press socket into the hole, pushing it in evenly and firmly until flush. (7) Pushed in the new type bulb that came with new Socket. Turned on power, and light came on. (8) screwed on new glass cover. (9) Lifted oven back onto the hinge prongs. (easier with two people to get the prongs aligned and into their door slots.) Worked door left and right to get it to lower down fully. Removed nails, lowered door, and put its 2 screws back on. (10) Poured a glass of wine.

Following your installation, the old part came out easily, with new part installing easily., oven heat is being regulated properly..with range pulled out for part replacement, got that area cleaned too

I watched the repair video on this site and another on YouTube before I started. The rear panel has a different shape and two additional screws on the bottom edge. The power clip was easy to manipulate.
This was an easy fix for a seventy year-old like me!

the hardest part was moving stove to trplace part

Slid oven out and took back shield off unplugged sensor took bracket screw out replaced sensor with new one.

First I removed the two wires from the back of the stove. I then removed the two screws that were holding the element in place. Installed the new one without problems

I removed all the screws that held the trim and inner frame to the outside window unit first. Then, I removed a protective glass from over the two inner panes. Next after removing the frame that held the two inner glass panes together, I took the broken inner glass pane out and replaced it with the new one. Then basically I just retraced my steps and had the door put back together in about 45 minutes. You just need to pay close attention to your disassembly so that you are able to put the pieces back together quickly.

Removed the ice brucket,
Removed the light shield by releasing one screw using a nutdriver.
Replacing the bulb and reinstalled the light shield.

Your web site is one of the best and most helpfull service sites I ever used. Just wish that in the future you will ship parts overseas.
