GE Microwave PF Error Code: What It Means and How to Fix It

By Dan Mercer · Published October 5, 2026 · Updated October 5, 2026 · Codes covered: PF, 888, 8888 · Sources

Verify in your manual: The pad that clears PF is labeled Cancel/Off, Clear/Off or Pause/Off depending on the GE model; check your owner's manual.

PF on a GE microwave stands for power failure. The microwave lost power for a moment, from an outage, a tripped breaker or being unplugged, and it's letting you know the clock and settings were lost. It isn't a fault, and one press of the right pad clears it.

Depending on the model, GE says you may see 888 or 8888 instead of PF. They mean the same thing.

What the PF code means

GE's support article says that after a power failure to your home, "when the power comes back on, you may see a "PF", "888" or "8888" code in the display on your Microwave Oven."

GE adds that you may also see it "upon initial installation or after the power cord was unplugged and plugged back in." So a brand-new microwave, or one you just unplugged to clean behind, will often show PF the first time it gets power.

GE's owner's manuals say the same in a single line: "A Power Failure has occurred." The fix is to press the cancel pad to clear the display, then reset the clock on models that have one.

Which pad clears it:

• GE's support pages say to touch CLEAR or CLEAR/OFF, or Cancel/Off.
• The JES1095 countertop manual says Cancel/Off.
• The GCST11N1/GCST11X1 manual says Pause/Off.

Look-alike codes that mean something else:

• F3: GE's manual says "A key has been activated for more than 60 seconds." Liquid on the control panel can cause it. GE's fault-code list calls it a "Shorted touch pad panel."
• LOC: the control panel is locked. GE says to press and hold Cancel/Off for about 3 seconds to unlock it.
• "18 power watch code": despite the name, GE lists this as an issue with the microwave's electronic control. That's a service call, not a PF.

Likely causes (most common first)

1. A power outage or flicker. Even a split-second dip can reset the clock and bring up PF.
2. The microwave was just installed or plugged back in. GE says this is normal.
3. A tripped breaker or blown fuse. GE's manual lists this first when the oven won't come on.
4. A loose plug. A plug that isn't fully seated can lose contact and cut power.
5. A shared or overloaded circuit. GE's manual says to plug the microwave into its own outlet "to prevent flickering of lights, blowing of fuse or tripping of circuit breaker."
6. An extension cord. GE's manual says not to use one.
7. A wiring or control problem. If PF keeps returning with no outages, and the plug and circuit check out, the house wiring or the microwave itself needs a pro.

How to fix it, step by step

Try the microwave after each step.

1. Press the cancel pad once. That's Cancel/Off, Clear/Off or Pause/Off depending on your model.
2. Reset the clock. Your owner's manual has the steps for your model.
3. Run a quick test. Put a cup of water inside and heat it for a short time to confirm it works normally.
4. Check the plug if PF comes back. Make sure it's fully pushed into the outlet. Over-the-range models are often plugged in inside the cabinet above, so look there.
5. Remove any extension cord or power strip. Plug the microwave straight into a properly grounded 3-prong wall outlet, as GE's manual requires.
6. Look at the breaker or fuse. Reset a tripped breaker or replace a blown fuse. If the breaker trips again, stop and see "When to call a pro."
7. Do a full power reset. GE says shutting off the breaker or fuse to the microwave for 30 seconds can clear a code. Switch it back on, then press the cancel pad.
8. Watch for a pattern. Note when PF shows up. If it appears whenever another appliance on the same circuit runs, the circuit is likely overloaded. GE recommends giving the microwave its own outlet.
9. Stop if PF keeps coming back with no outage. If the plug, outlet and breaker are fine and PF still appears on its own, the problem is in the wiring or the microwave. Call a pro.

Test the part

There's no part a homeowner should test for PF. The likely causes are outside the microwave (power, plug, circuit), and the parts inside sit next to a high-voltage capacitor. Repair Clinic warns that capacitor can hold enough charge to cause serious injury or death, even after unplugging. Stick to these outside checks.

1. Unplug the microwave or switch off its breaker. Do this before you handle the plug or cord.
2. Inspect the cord and plug. Look for cracks, scorch marks, bent prongs or a missing ground prong. If you see damage, don't use the microwave.
3. Look at the outlet. Check for scorch marks, a loose or wobbly receptacle, or a plug that falls out easily. Those are jobs for an electrician.
4. Check what else shares the circuit. Note any appliances that run on the same breaker.
5. Plug back in firmly and restore power. Press the cancel pad and see if PF stays away.
6. Stop here. Don't remove the outer case or any panel, and don't take any meter readings inside the microwave.

If PF keeps returning and everything outside looks fine, request service.

Safety notes

When to call a pro

A single PF after an outage needs nothing more than the cancel pad. Bring in help at these points:

• An electrician if the breaker keeps tripping, the outlet is scorched or loose, lights flicker when the microwave runs, or the microwave has no dedicated outlet and you need one added. Outlet and circuit work is not a DIY task for most owners.
• GE Appliances service if PF appears with no outage after you've checked the plug, cord and breaker, if the cord is damaged, or if the display shows F-codes or the "18 power watch code." GE says fault codes should be diagnosed by a trained service technician.
• Anything that means opening the cabinet. Control boards and internal wiring sit next to the high-voltage parts. That's a pro-only job.
• Your microwave is under warranty. Request service instead of opening it.
