A frequent reason for a microwave clock constantly resetting is power interruptions. Furthermore, if your power source, control panel, or display screen is showing signs of wear and tear, your microwave clock might begin to malfunction.

Reasons Why Your Microwave Clock Keeps Resetting

1. Adjust the Clock Setting

When encountering an issue with a malfunctioning microwave clock, always begin by verifying if it's set correctly. Surprisingly, many cases involve the clock not being set properly from the start.

To set your microwave clock, press and hold the "Clock" or "Time" button until the display shows flashing zeros. Input the correct time and press "OK" or "Start."

Please note that the process for resetting your microwave clock may vary depending on your specific microwave model. Consult your owner's manual for detailed instructions.

2. Address Short Power Outages

Short power outages are a common cause of microwave clock resetting. The microwave's clock is directly linked to the AC power current, and interruptions can cause it to reset to 00:00.

Short power outages can occur in various settings, including multi-family homes and can be initiated by your electricity provider. If the clock keeps resetting without a clear reason, and other solutions don't work, contacting your power company may be necessary to inspect power line issues.

3. Check for a Faulty Power Supply

If your microwave clock won't stay on or continuously resets, there might be an issue with the power supply. Damaged power cords can lead to short circuits that reset the clock. If you have a damaged cord, it's advisable to replace it.

Here are the steps to replace your microwave's power supply:

  1. Start by unplugging your microwave from the wall outlet.
  2. Use an electrician's screwdriver to carefully remove the back panel of your microwave.
  3. Locate the cable harness that connects the power supply to the rest of the microwave and disconnect it.
  4. Attach the wire that goes from the power supply into the ground, connecting it to the metal base of the microwave.
  5. Insert your new power supply into its designated housing.
  6. Reattach the grounding wire to the metal case of the microwave using a screw.
  7. Plug the power supply cable harness back into the microwave.
  8. Securely reattach the back panel of your microwave and plug it back into the wall outlet.
  9. Attempt to reset your microwave's clock.

If you feel uncertain or uncomfortable about handling the power supply replacement, consult a certified electrician.

  2. Locate the control board, which can be positioned either inside the body of the microwave or behind the front control panel.
  3. Disconnect the cable harnesses that are attached to the control board.
  4. Unscrew the control board from its housing.
  5. Unpack your new control board and fit it into the housing previously occupied by the old control board.

  7. Reattach the back panel of your microwave.
  8. Plug your microwave back into the power source.
  9. Reset the clock on your microwave.

Here's a step-by-step guide on how to swiftly replace an old display panel on a countertop microwave:

  1. Begin by unplugging your microwave to ensure safety.
