Haier range display shows PF and clock resets after a power interruption

Safety first: If you suspect wiring issues, turn off power at the breaker before inspection.

• Reset clock: Press Clear/Off then set the time according to the user manual. PF will usually clear.
• Check power stability: If PF appears frequently without known outages, have an electrician check the circuit for loose connections or voltage drops.
• Inspect terminal block: With power off, remove the rear cover and inspect the range terminal block for signs of heat damage or loose screws. Tighten or replace as needed.

PF itself is informational; address underlying power issues if they recur.
