Maytag Range PF Error Code — What It Means
PF stands for power failure. The electronic control board detected a loss or interruption of supply voltage long enough to stop operation, or saw a brief disturbance during startup. This code does not mean a cooking component has failed. It tells you the range control lost power or read unstable incoming voltage at some point. The code can appear after an actual outage, during a brownout, or if the supply wiring is loose enough to cause intermittent drops in voltage.
Common Causes
- Actual power outage or brownout A utility interruption or voltage sag on your home circuit will trigger PF when the control loses supply.
- Loose connection at the terminal block Corroded or under-torqued wire lugs where the range cord or junction-box feed lands can create intermittent voltage drops that the control sees as a power failure.
- Poor contact at the circuit breaker or receptacle A loose breaker or worn receptacle causes unstable incoming power, especially under load when the oven draws full current.
- Line noise or voltage sag during startup Maytag documentation notes that brief disturbances on the power line when the range energizes can display PF even if supply recovers immediately.
- User input too soon after power restoration Pressing keypad buttons before the control finishes its startup delay can cause PF to appear, according to Maytag guidance for dryers using the same code.
- Faulty electronic oven control board If incoming power is verified correct and the code will not clear, the clock or control board itself may be misreading or losing supply voltage internally.
Step-by-Step Fix
- Turn off the range circuit breaker for at least five minutes to fully discharge the electronic control, then restore power and wait without touching any buttons for at least ten seconds to allow the startup sequence to complete.
- Check the circuit breaker for corrosion, overheating marks, and firm seating in the panel, and verify that both legs of the 240 V feed are tight at the breaker terminals.
- Inspect the range cord and receptacle (or the junction-box wiring if hardwired) for loose, discolored, or burned connections, tightening all terminals and replacing any damaged components.
- Verify incoming voltage at the terminal block inside the range by measuring L1-to-neutral and L2-to-neutral with a multimeter under no-load conditions, confirming each leg reads approximately 120 VAC and L1-to-L2 reads 240 VAC.
- Reseat the control-board wiring harness and keypad ribbon at the clock or electronic oven control to rule out a poor connection in the control path.
- Run a test bake cycle at a moderate temperature and observe whether PF reappears under load, watching for flicker or dimming that would indicate unstable supply voltage.
- Replace the electronic oven control board if all power-supply checks are normal and the PF code persists or returns immediately after reset, following your model’s service sheet for the correct part number.
Parts Often Needed
| Part | Notes |
|---|---|
| Electronic oven control board (clock) | Amazon | Order the exact part number listed in your range’s service sheet when incoming power is verified correct but PF will not clear. |
| Range power cord and terminal block kit | Amazon | Replace together if the existing terminals show heat damage or corrosion that cannot be safely cleaned and retorqued. |
When to Call a Pro
Call a qualified appliance technician if you are not comfortable working inside a 240 V appliance, if voltage measurements at the terminal block fall outside the expected range, or if the PF code returns after you have verified and tightened all supply connections. A pro has the tools to load-test the incoming circuit, measure voltage under full oven draw, and safely replace the control board with the factory-correct part. Also call if you find evidence of arcing, melted insulation, or burned terminals anywhere in the supply path, since those conditions require immediate repair to prevent fire hazard.
