Whirlpool WMH32519HZ user manual

There could be a few possible reasons why your microwave fan automatically turned on:
1. Cooling Function: Some microwaves have a cooling function that automatically turns on the fan to prevent overheating. This function may engage if the microwave is being used for extended periods or at high power settings.
2. Sensor Detection: The microwave may have a built-in sensor that detects excessive heat or smoke and automatically activates the fan to remove any odor or smoke particles.
3. Cooking Function: Certain cooking functions in the microwave, such as grilling or convection cooking, may require the fan to be turned on to circulate hot air or exhaust fumes.
4. Ventilation System: The microwave may share a ventilation system with other appliances, such as a range hood, which causes the fan to automatically turn on when it detects heat or steam from cooking.
If you are unsure about why the fan turned on or if it is occurring unexpectedly, it is recommended to consult the appliance's user manual or contact the manufacturer for further assistance and clarification.

Your Whirlpool microwave's fan might continue running for several reasons:
1. Cooling Feature: Sometimes, the internal components of the microwave need to cool down. The fan will continue to run until the microwave has cooled down sufficiently.
2. Door Issue: If your microwave door is not closing properly, or its switches and latches are faulty, this might trick the microwave into thinking it's still running and keep the fan on.
3. Sensor Issue: Modern microwaves come with a humidity sensor that detects the amount of steam in the microwave. If this is faulty, it might be causing the fan to run continuously.
4. Faulty Circuit Board: If there's a malfunction in the control board's programming, it could cause the fan to keep running.
If you're having trouble figuring out the issue, it's best to contact a professional or Whirlpool’s customer service for further assistance.

There could be several reasons why your Whirlpool microwave is not working. Here are some common issues that you can check:
1. Power supply: Ensure that the microwave is properly plugged into a working power outlet and that the circuit breaker or fuse has not tripped.
2. Control panel: If the control panel or display is not functioning, there may be a problem with the keypad or control board. Make sure it is not locked or that there are no error codes displayed.
3. Door switch: The microwave has safety switches that detect whether the door is properly closed. If the door switch is faulty or not activating properly, the microwave may not start. Check if the door is closing properly and if the switch is working.
4. Start button: If the start button is not working, there might be a problem with the control panel or a faulty connection.
5. Internal fuse: Microwaves also have an internal fuse that can blow if there is an electrical surge or failure. You can check if the fuse is blown by using a multimeter to test for continuity.
If none of these troubleshooting steps fix the issue, it might be best to contact a professional technician or Whirlpool customer support for further assistance.
