SOURCE: I keep getting a beep

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.

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.

SOURCE: NTC cover message after replacing fuse

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).

Tip

Error Code F8E5


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.

Technika rangehood parts


please follow the steps and fix it. God bless you

  1. Light bulbIf your microwave light bulb is not working, perhaps it has blown. The first step is to replace the bulb and power on the microwave. If this does not correct the issue, the next step is to check the socket and wiring to verify if that is the problem.
  2. Light bulb socket & main control boardIf your microwave light bulb is not working after the installation of a new bulb, check the light socket as well as the wiring to ensure they are properly operating. If these sources are functioning properly, the next step is to check for a faulty control board as a possible root cause to your microwave light bulb malfunction.

Microwave says NCT is open


That would probably be "NTC", which stands for "negative temperature coefficient", which is just a fancy name for a thermistor.

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

There should be a technical sheet hidden behind the grille or controller. It will show you where components are located and how to test them.

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.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download Whirlpool owner's manuals and installation instructions here.

Baumatic rangehood bah9005 the switch pushes in and the lights dont work , motor works when electrical switch at wall is on


Thank you for using FixYa. It sounds like there is obviously power getting to the rangehood ( the motor works) and I would suspect that it is just the bulbs that have blown.
