20 Most Recent Whirlpool GH4155XP Microwave Oven - Page 8 Questions & Answers

Try this link ... owners manual ... go to page 15 https://www.searspartsdirect.com/partsdirect/user-manuals/gsc309pvs02-whirlpool-parts-manual It shows how to remove the door and talks about how to release the latches. It sounds like whomever cleaned it ... may have removed the door and not reinstalled it correctly?? Helpful?

Google the make/model and download the manual from the Whirlpool website.

Have you had trouble with the cooktop lights recently? The circuits for both lights and fan can be affected if so. Does it happen when you are not cooking on the stovetop? Your product support page is here, where you can get the owner's manual, installation instructions, parts list, etc. You can order Whirlpool parts from the Pros here. If your controller needs repair, I do that. Details here.

A door switch may be defective due to opening the door while it's cooking instead of pressing the "stop" pad first, or a switch's mount is loose, misaligned, or broken. See my help files here: http://www.microwavecontrol.com/safety.htm http://www.microwavecontrol.com/disassembly.htm http://www.microwavecontrol.com/doorsw.htm Feel free to contact me by e-mail directly through my site above if you need further help.

There are two thermal switches, a high voltage capacitor, a double diode, the transformer and the magnetron itself that could be the problem . I am going to say straight up that you could get electrocuted if you dont know what to do here. To test:

HV TRANSFORMER

Remove lead wire.

Measure the resistance of the winding using an ohm meter

Primary winding 3 ohm (approx.)

Secondary winding 100 ohm (approx.) Filament winding 0 ohm (approx) HV CAPACITOR Remove lead wire Measure the resistance using an ohm meter set to R*1000 Terminal to terminal should momentary indicates several ohms but gradually increases to infinite. Terminal to case should show infinite.

MAGNETRON Remove lead wire. Install the magnetron gasket in the correct position. Check that the gasket is in good condition. Measure the resistance of the filament terminals. Normal magnetron should be less than 1 ohm. Measure the resistance between the filament terminal to chassis. Normal magnetron should be infinite.

HV CAPACITOR

Remove lead wire

Measure the resistance using an ohm meter set to R*1000

Terminal to terminal should momentary indicates several ohms but gradually increases to infinite. Terminal to case should show infinite.

F8E5 Exhaust air template detection failure 1. Press CANCEL - CANCEL - START, verify failure code, and then press CLOCK/OPTIONS to display the exhaust air temperature sensor reading. Verify the sensor temperature reading is at room temperature (typically 50?F to 90? [10?C to 32?C]) and verify failure code. If failure code matches complaint, continue to Step 2. 2. Unplug microwave oven or disconnect power. 3. Disconnect sensor from ACU PCBA. 4. Measure HF NTC resistance between connector pins and confirm reading is between 9.5k??and 10.5k??at room temperature. If measurement is not correct, or if a short or open circuit is found, replace sensor. 5. Replace all parts and panels before operating. 6. Plug in microwave oven or reconnect power. 7. If the sensor temperature reading is still not correct, replace ACU PCBA. 8. If failure does not appear, stop.

It's broke

Usual failures of a microwave are the diode, the high voltage capacitor and lastly, the magnetron itself. These are all HIGH voltage components. You really need to be careful when working on them.

Whirlpool maintains a library of free downloadable literature for nearly all of their products. Your MH7140XFZ microwave oven is no exception. The site contains owner's manuals, installation manuals and parts lists. Your answer will be found in one of the two installation manuals. You should review both to determine which best applies for your particular installation.

Referring to manufacturer's literature is always the best source for information - so I did not want to paraphrase anything in it - especially since it is readily and freely available.

I hope this helps & good luck! Please rate my reply - thank you.

Which microwave model do you have? Most of the Whirlpool microwaves that I know only have a 12-hour clock. They do not indicate AM or PM. To set the ones that I know, press Clock. Type in the current time in a 12-hour format. Press Clock again. The only model that I find quickly that has an AM/PM option is the GH7208XR. On that model, start with the main menu displayed on the LCD screen. Touch Settings and Info. Next press Clock. Then press Adjust Time. Follow the instructions to set the time and the AM/PM setting. I'll assume you use the +/- buttons. To hide the clock, get to the Clock Screen. Press Adjust Time and Hide Clock to return to the main menu. See these two pages of the manual for this model: https://www.manualslib.com/manual/190817/Whirlpool-Gh7208xr.html?page=9#manual and https://www.manualslib.com/manual/190817/Whirlpool-Gh7208xr.html?page=12#manual Current Whirlpool over-the-range models sold in the US are listed here: https://www.whirlpool.com/kitchen/cooking/microwaves/over-the-range.html . Other Whirlpool appliance manuals are available from the Owner Support page: https://www.whirlpool.com/services/manuals.html. I hope this helps. Please add a comment with the model number for a more accurate information on setting the clock. The model number should be inside the microwave on the rim. Usually it's on the bottom of the door frame near the door hinge. Cindy Wells
