MMW7730DS02 Maytag Microwave - Instructions

Removed and replaced above named parts, rewired.Be sure to tighten all nuts that secure wires. I believe this is what caused the problem.

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

I used a Google search to show how to access the area behind the front panel. There was a folded paper copy with a schematic and wiring diagram in that space.Then I used a multi-meter to determine which of the THREE micro-switches was causing the problem. I called your help line and ordered a replacement switch. The switch was delayed in transit so your agent credited me with the cost of shipping.

When the part arrived, it had three terminals instead of two as shown in the on-line picture but that did not cause any difficulty in using it. It took about 20 minutes to remove and replace the old switch.

All seems to be working well now.

Finding which of the THREE switches was the problem was the most difficult part of the repair. All three "clicked" but the defective one did not click as easily. It needed to be depressed more than the door latch can would provide. Old age?

Purchased 2 piece broiler pan from this site

IMPORTANT: DO NOT TOUCH THE REPLACEMENT LAMP WITHOUT WEARING CLEAN GLOVES. FILM OR FINGER PRINTS ON THE LAMP GLASS WILL CAUSE PREMATURE FAILURE OF THE LAMP.

Remove the 4 screws on right and left mounting rails that hold the unit to the kitchen cabinet.
Remove the oven door
Remove the chrome oven vent strip below the oven door. This allows a pry point beneath the combo microwave oven assembly to lift up the unit while pulling it out. (Assembly weighs 250 pounds)
Pull the unit out from the cabinet housing about 2-3 inches to reveal the right and left sides and the 4 screws holding the the control panel.
Remove the 4 control panel screws and pull off the face of the control panel
Remove the 2 harness connectors and the ground wire holding the control panel to the unit.
Unclip the circuit board above the lamp connector and slide it back out of the way. The lamp is now accessible.
Remove the lamp spring holding the lamp to the cabinet.
Remove the old lamp
Install the new lamp using clean gloves
Reassemble in reverse order.

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.

Had a technician from Home Advisor to check the problem out with my Whirlpool Double oven(1 1/2 old). Paid $60 to find the problem. According to the technician problem was control board and cost of labor and parts $465.00
Jumped on Part Select website, placed a question with my stove problem through the chat. Immediately they answered my question and told me the problem was the Terminal Block. Cost of part and shipping $25.00. Replaced it myself and everything works fine.
Thank you, Thank you Part Select for your help and honesty.

Sincerely
Peter from Maryland
