PF means power has been interrupted to the appliance, from an outage, a tripped breaker or a brief flicker. The stove stops what it was doing and waits for you. LG stove display What to do when PF shows on the stove ### Kind of code Mode, not a failure Something the stove was switched into, often by accident, rather than something that broke: a control lock pressed while wiping the panel, a Sabbath setting, a showroom demo mode that lights the display and heats nothing, a reminder that a spot on the stovetop is still hot. No part is worn out, and the stove's own keys put it right. ### Usually leads to No repair Press CLEAR/OFF and reset the clock if needed. ### Shows up as Stove Display Blank or Flashing The clock and display on the stove have gone dark, or they flash the time, a word or a string of characters and ignore the keys you press. ### Make LG The Korean electronics maker whose freestanding and slide-in stoves often come with app controls. ### Source LG Help Library: range error codes list (Wayback, 23 Jun 2025) Where PF is documented: LG's Help Library code list (Wayback copy of 23 June 2025); the list names no models, so the rating label decides whether your stove can show it. ## Before you book, in this order. Each step comes from LG's own guidance for PF on its stoves. Follow it to the end: the last card says whether this is a visit. 01 Press CLEAR/OFF and reset the clock if needed. 02 Start the cooking function again and check that it heats. 03 If PF keeps appearing without an outage, have the breaker and cord checked, and book a visit if the supply is sound. ### Cleared? The stove is working again and no part was needed. If the same letters come back while a burner or the oven is on, or the stove switches itself off again in the middle of dinner, book it as a new problem. ### What not to do PF is not a stove failure on its own. It records that the power dropped, which is outside the stove. ## What you may notice with it. The stove problems PF tends to arrive with. Answer these at the stove before anyone is booked.

Press CLEAR/OFF and reset the clock if needed. ### My LG shows PF every morning. What could cause that? Something is interrupting its power at night, such as a weak breaker or a loose connection. That is worth checking even if the stove seems fine. ### Do I need to reset anything on my LG after PF? Press CLEAR/OFF, set the clock if it was lost and restart what you were cooking. ### Was food in my LG oven safe after a PF during a long bake? The oven stopped when the power dropped. Judge the food by how long it sat without heat, and restart or finish cooking it. --- **[Read on the site: LG stove shows PF after the power comes back](https://stoverepair.center/error-codes/lg-pf/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
