Question about Whirlpool MH1140XM Microwave Oven

2 Answers

Complete functioning control panel but nothing works.

Manufacturer: Whirlpool Model no: MH1140XMB-1 The other day, I went to replace the range light and ended up breaking the screw connector from the bulb (the installer glued the bulb in place.) so I flipped the relay for the microwave, used my pliers to remove the rest of the bulb, (didn't have a replacement bulb so I just screwed the cover back on.) and then flipped the relay back on. The control panel came up like it had lost power, so I pressed the clock button and re-entered the time. My wife then tried using the oven, and it let her enter the cooktime, and even hit start. At which point the oven should come on, nothing happens, but the timer starts counting down like it's cooking. Upon investigating other functions, it also appears that the vent fan isn't working, and upon checking the voltage to the empty bulb with my multimeter, it was 4VAC, no matter how the switch was set on the control panel. Any tips would be much appreciated.

This is a problem with the control panel assembly, which we repair nationwide for $32.50 postpaid. Sometimes the bulbs short when they fail, and that damages the control board. This also can happen when bulbs are removed or installed without first unlugging the oven or turning off the breaker.

    You said it just like it happened to me; the bulb broke loose and their was a wad of hot glue there. You in the world turns off the juice to change a light bulb, not me. I guess I will replace the circuit board.

I have an older Whirlpool over the range microwave. 2001 model#MH6150XHQ-1 I went to start it and poof, it went dead. Was it a fuse? If so where are they located and how do I get one for it?


There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find your mini-manual, or if you want to look at it before removing the controller, you can download it here (just enter your model number).

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Hamburger in foil wrap put in microwave - shorted unit out


Hi- The first thing here is safety. If the power supply is good- 120v at outlet- then address the fuse in the cabinet. Open door, remove screw(s) holding control panel, and tilt out panel. Fuse should be visible. Check for continuity. If bad, replace with 15amp appliance fuse. Plug in and check for operation. If fuse blows again, unplug and start looking at a new microwave. Let me know if this info helps. Have more if needed- Thanks- Ed

Whirlpool MH1140XMB-2 mic won't start


This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.


Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.

Or you can view and download it here.

At
our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you've recently had trouble with your cooktop lights, one may have shorted, causing a problem on your control circuit board, which we regularly repair for $39.95 in about a week or so with a one-year guarantee.

Whirlpool Microwave Hood combination Model MH6150XM turned itself on without anyone touching it. The oven and the fan went on. It continued to operate when the microwave door was opened. We unplugged...


Direct spraying of cleaners on the keypad and steam from the cooktop can short the keypad.

Luckily, it dried out. Sometimes it doesn't, and the keypad has to be replaced.

I always recommend that you spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

And I always recommend that you use the vent fan when cooking on the stove top to keep heat, steam, and grease out of the controls.

No display, no light, no fan, microwave dead!


There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

It may be the fuse, which is located in the upper area behind the control panel.


If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

(Don't be confused by the base or hood thermostat, which is on the floor of the chassis. It will read normally open).

The fuse and magnetron thermostat can be checked with out taking the oven down from the wall, but if you need to check the oven thermostat, you will need to pull it from the wall.

To help with that, you can download Whirlpool owner's manuals and installation instructions here.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.
