KEMS377GWH4 KitchenAid Microwave Oven Combo - Instructions

Oven stopped heating after attempting a self cleaning cycle. Problem turned out to be failed thermal fuse component. This is an easy repair and well worth the attempt given the replacement cost of the oven.

First step was to locate and shut off the two circuit breakers supplying power to the oven. Then I locked the panel to ensure someone didnt re-engage the breakers while I was working on the unit. (Lock out / Tag out).

Second step was sliding the oven out of the cabinet - this unit is located below a cooking top and was just the perfect height to allow a furniture dolly to be used to support the oven as I slid it out.

The unit is 'hard wired' (i.e. no power plug) so it can only be pulled out so far from the cabinet, but there was sufficient reach to allow access to and removal of the sheet metal cover at the rear of the oven to expose the thermal fuse and the read wiring. I proceeded with care, assuming the power was still on and once the terminals of the thermal fuse were exposed I performed a voltage measurement to ground on each side of the fuse to ensure power was in fact off.

Then I used an insulated pliers to gently remove the wire harness at each side of the fuse, and once the wires were removed I performed a continuity check of the suspect fuse, and confirmed it was an open circuit (i.e. failed).

Removal of two more screws allowed the fuse to be removed and the new fuse was installed, reversing the procedure.

This was followed by replacement of the rear sheet metal and finally sliding the oven back into its place in the cabinet using the furniture dolly. This is a single oven but still very heavy and has some sharp sheet metal edges likely to cause cuts if not handled with care so the dolly and a second set of hands (and good gloves) are nice to have.

Finally, after inspecting the oven door gasket and other air vents around the outside of the oven to identify suspect causes of the overheating event that tripped the fuse, the air vents above and below and within the door were cleared of dust-bunnies and other debris that had collected, possibly causing interference with the air flow that cools the area in between the oven and the cabinet. This blockage may have been the root cause of the fuse failure - i.e. the air did get too hot back there and had the fuse not tripped it would have been dangerous. The door gasket looked fine although its also an easy replacement and does not require oven removal.

The new part fit perfectly - it was a different design than the original part that shipped with the oven but appears to function perfectly so no complaints. The trip temperature is identical to the OEM part based upon the nomenclature on the back of the OEM and the replacement fuse part.

Unlocked the power panel and turned on the two breakers to the oven, set the clock and checked operation and its functioning great now.

Have not run a self cleaning operation since the repair but that is the next step and now that those door vents are clear I suspect that the fuse wont trip again.

Lesson Learned: Check those vents for obstructions.

Similar oven selling at discount because its the end of the model year is now priced at over $1100. Fixed our unit for $50 and the added cost of a $20 furniture dolly that I already wanted to buy.

Give this repair a try its a piece of cake and well worth the effort.

I have a rental and the tenant called. She said that she had a repair man out to fix the oven but he couldn't~that it needed to be replaced as he could not get parts.I contacted your company via phone and the person was so helpful~he asked the problem, looked up the model and advised me on this!It works like a brand new oven!Thanks you

easily IDed parts; ordered, here 3 days later. very convenient. no hassle. no wasted time going from place to place or calling everyone in yellow pages.

I just placed the tray in and was done. The kicker is that i cannot use my microwave without the tray. so i was without my microwave for 2 weeks before i called parts select. they were quick and fast.

Used a Phillips head screw driver to remove cover that was covering the over bottom 1/3 of the installed gasket. I then used flathead screwdriver to help remove gasket from the "pins" that were in the gasket that held it to the oven. Installed new gasket inserting pins into the oven. Then I installed cover over bottom 1/3 of gasket. Overall process was very easy

Replaced oven temp sensor, removed oven door and interior racks for easy access to oven upper rear sensor access. Used philips head screw driver to remove both screws, gently pulled old senor out of reat oven wall until electrical connector clear of rear wall, disconnected connector, connected new sensor and gently pushed wiring and connector back into opening, reinstalled door and racks. Ran open thru cycle and used oven thermometer to check temp. fast easy install

The website and diagram of my oven helped me know exactly what was wrong and where to locate the problem. I simply removed the oven door and the trim, pulled the oven out of the wall. After removing the back panel I located the part and put in the new part. Then reversed the procedure.

Removed the door and laid it flat with the cracked glass facing up. applied duct tape to the broken glass to help hold it together. Removed the screws from the frame holding the glass. lifted the frame off,removed the broken glass and replaced it with the new piece. replaced the frame. and put the door back on the oven.

This is the third time that the bulb went out.It took two Sears service technitions to remove the entire appliance out of the cabinet. The entire top has to be removed and the insolation has to be pulled back to get to the electrical wire. I am waiting for an appointment to get Sears to do it again. The door springs have broken and you have to make sure the door is closed before walking away. It has a heavy glass and the weight is pretty heavy. Robert.

Removed all terminals and block mounting screws. Repaired one burnt terminal and reassembled. Replacement part was an exact fit and reassembly whnet very well.

My husband took the back off and replaced it. The repairman suggested pulling the range out into the floor to run the self clean mode. I have owned several such ranges and have never had to do that and won't now. Easy Clean Oven Cleaner will be the next thing I use.

cut power off and placed sturdy table same height as bottom of oven in front of oven. removed trim screws. pulled oven out onto table. removed top cover and panel on left side . tested transformer to be sure it was bad. then replaced transforner

The replacement of the blower was an easy repair. Just had to remove two back panels of the oven and the blower was then very accessable. Just remove the two electrical wires and then three screws and the blower came right off. Put the new blower on with the three screws and replaced the 10 or 12 screws holding the back panels and the job was complete!. The difficult part of the job was removing the combo unit from the cabinet to access the back panels. That part took some effort. Had to build a platform to slide the oven out onto after I disconnected the electrical feed wire (#6 wire) located in a junction box in my attic. Once that was done, the actual blower replacement was simple. The turntable motor was a different story...Although replacing the turntable motor was going to be as easy as replacing the blower motor, I couldn't access the underside of the microwave without disassembling the whole combo unit cabinet! That was very disappointing to me that Whirlpool didn't make that part easier to access, so I didn't replace the turntable motor. Too bad but we are just going to live with the turntable not turning!!

The replacement turntable we received was an exact duplicate of the original. It was as easy as rinsing the new turntable, taking the old turntable out and putting the new one in.

Ordered a new one, put it in place in less than one minute.
