--- title: "GE Profile F1: the thermal sensor opened from heat in the cavity" description: "What F1 means on GE Profile F1: the thermal sensor opened from heat in the cavitys, what to check before booking, and when it is not a failure at all." url: "https://microwaverepair.center/error-codes/ge-profile-f1/" --- # GE Profile F1: the thermal sensor opened from heat in the cavity The microwave's thermal sensor guards against overheating. ## What F1 actually means. The microwave's thermal sensor guards against overheating. GE lists F1 as that sensor reading open because the cavity became excessively hot, for example from a long empty run or food left to burn. The control stops heating to protect itself. GE Profile microwave display What to do when F1 shows on the microwave ### Kind of code Sensors and temperature The control has stopped trusting what one of its sensors reports: the cook or humidity sensor that ends a sensor reheat when steam rises, or a thermal cutout that trips when the cavity or the magnetron runs too hot. A cutout that opens stops the microwave mid-cycle and often recovers once it cools; one that keeps tripping, or a sensor program that shuts off at once every time, needs the sensor, its wiring or the airflow behind it checked. ### Usually leads to Microwave control board and touchpad repair Tracing a dead display, keys that do not answer or a code that keeps returning to the keypad, the ribbon, the relays or the main board, and replacing only the part that failed. ### Shows up as What a Microwave Error Code Is Telling You A microwave error code may be a letter and a number on the display, a lock or demo word, a row of dashes, or a beep with a blinking clock, and it can show while the microwave still heats or block every key until it is cleared. ### Make GE Profile GE Profile microwaves repaired where they hang or sit, whether it is the vent fan, the cavity lamp, the keypad or the heat that gave out. ### Source GE Appliances microwave code article, linked from the PVM9005SJSS owner center F1 comes from the GE Appliances code article linked on the PVM9005SJSS owner center; the PVM9005 manual prints no F-codes. ## Before you book, in this order. Each step comes from GE Profile's own guidance for F1 on its microwaves. Follow it to the end: the last card says whether this is a visit. 01 Press Cancel/Off and let the microwave cool completely with the door open. 02 Switch the breaker that feeds it off for 30 seconds, then back on, as GE suggests. 03 If F1 returns on the next normal cycle, book a visit; the sensor, its wiring or the airflow around the unit needs checking. ### Still there? It usually turns into [microwave control board and touchpad repair](https://microwaverepair.center/services/microwave-control-board-and-touchpad-repair/). Book with the code and the model number. ### What not to do F1 does not by itself mean a fire, though anything burning inside should be handled with the door kept shut. It is also not the same as the OVEN TOO HOT message, which only blocks sensor programs and clears as the cavity cools. ## What you may notice with it. The microwave problems F1 tends to arrive with. Answer these at the microwave before anyone is booked.

Press Cancel/Off and let the microwave cool completely with the door open. If it comes back, it needs a visit. ### What should I do if my GE Profile hood microwave shows F1? Let it cool, reset the breaker for 30 seconds and try an ordinary cycle. A repeat F1 needs a technician. ### Can a blocked vent cause F1 on a GE Profile microwave? It can add to the heat the sensor sees, so on a hood combination the filters and vent path are checked along with the sensor. ### Is F1 dangerous on a GE Profile microwave? F1 means the control shut heating down, which is the protection working. Do not keep restarting it if it returns. --- **[Read on the site: GE Profile F1: the thermal sensor opened from heat in the cavity](https://microwaverepair.center/error-codes/ge-profile-f1/)** **[Book a visit with MicrowaveRepair.center](https://microwaverepair.center/schedule/)**
