Reported on: WRF535SWHZWRS325SDHZWRX735SDHZ

What Causes This Error

1

Power surge or brownout

high

A voltage fluctuation from the utility damaged components or tripped internal protection.

2

Faulty power cord or outlet

medium

The power cord has internal damage, or the wall outlet isn't providing proper voltage.

3

Control board power supply section failure

medium

The voltage regulation section of the main board has failed.

4

Tripped internal fuse or thermal cutoff

medium

An internal safety fuse blew to protect the appliance from damage.

How to Fix Error PO

  1. 1

    Unplug and wait 10 minutes

    A longer reset time (10 min) allows capacitors to fully discharge and all thermal protections to reset.

  2. 2

    Check your circuit breaker

    Go to your home's electrical panel and make sure the breaker for this appliance hasn't tripped. Flip it fully off then on.

  3. 3

    Test the outlet

    Plug something else into the same outlet (a lamp works) to verify the outlet has power. If nothing works, the outlet or circuit has an issue.

  4. 4

    Try a different outlet

    If possible, plug the appliance into a different outlet on a different circuit to rule out outlet/wiring issues.

  5. 5

    Inspect the power cord

    Look for cuts, burn marks, bent prongs, or a loose-feeling connection at the back of the appliance. A damaged cord should be replaced.

  6. 6

    Check internal fuses

    Some appliances have internal fuses (especially microwaves and ovens). With the appliance unplugged, remove the access panel and look for a ceramic or glass fuse. Test continuity — no reading means it's blown.

    Microwave capacitors retain lethal voltage — do not open a microwave without professional training.

Replacement Parts

When to Call a Professional

If the outlet itself is the problem, if you suspect a control board failure, or if it's a gas appliance with electrical issues

  • Electrical wiring issues in your home require a licensed electrician
  • Control board power supply failures are complex to diagnose
  • Combining gas + electrical problems creates safety risks
