Question about Whirlpool Microwave Ovens

1 Answer

I keep getting a beep then (NTC open call for service) in the window. What is NTC and what would cause this message? My microwave hood combination Model#MH2175xst-o is working fine except for the message.

It's a "thermistor", a type of temperature sensor.

NTC stands for negative temperature coefficient. When the temperature goes up, its resistance goes down, telling the controller the temperature.

Yours has failed and needs to be replaced.

If you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

NOTE: 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.

Our microwave does not consistently come on. When we put in the time to cook it tells us to open/close door. If the cavity light comes on then it works, if not it doesn't work. Please HELP! Thank you


Sounds like you have one or more faulty micro-switches for the door. They are not expensive to get, but your service center will likely charge you a lot to fix it. If you are handy, you can pull the case off and replace them yourself.

Twice my new kenmore microwave has just started beeping with the error code E11 appearing on the screen.Have to unplug it to stop it. WHat is going on?


I think this microwave oven uses an inverter to control the power output of the magnetron. Usually the microwave will advertise this feature with a trade name like "accu-wave" or "true-power" or some similar label on the front of the microwave. Assuming that is the case here, then the E11 error means a bad inverter

NTC OPEN CALL FOR SERVICE


The magnetron thermal protector is open. It is probably defective.

From page 7 of your owner's manual:

All Tones (combination oven models only)

All of the above tones are preset on, but can be turned off.
To Turn Off/On: Touch and hold STOP TIME for 5 seconds. A

The volume is preset at high, but can be changed to low.

To Change: Touch and hold the number pad “7” for 5 seconds. A

REMINDER TONES

The Timer and Timed Cooking reminder tones are preset on, but
can be turned off. Reminder tones do not include end-of-cycle

turned off, the reminder tones cannot be independently turned
on.

Whirlpool Microwave Hood Combination MH3184XPS-0 (October 2004), for no reason at all, this morning keeps beeping and running the power setting down from 10 to 1, and just keeps doing it in rapid sequence....


Ours just started doing this exact same thing this past Friday - 12/11/09. What's going on? The cook power just starts beeping all by itself and going from 10 down to 1 over and over again. It may stop momentarily, but then starts again within a minute or so - it's constant until we unplug it. We plug it back in and within a few minutes it starts doing it again. What gives?

NTC cover message after replacing fuse in my whirlpool microwave MH1170xsb


The "negative temperature coeffecient" (NTC) thermistor was left unplugged after reassembly or it is defective.

It is the hood thermistor, and should be plugged into connector P4 on the circuit board.

I think it should be at the bottom of the board, on a little tongue-like protrusion, as shown in the attached photo.

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 yours, or if you want to look at it without disassembling the oven, you can download it here (just enter your model number).

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

I keep getting an f1 message and constant beeping from my oven


F 11 code. it is a touch pad error.
If you just cleaned the control panel it may have water in the panel causing a key to stick.
If after a day or 2 it hasn't dried out - then you will need to replace the touch pad.
