# SKS F13: the speed oven's low thermistor reads shorted

F13 is the shorted reading from the same sensor that gives F12 when it reads open.

## What F13 actually means.

F13 is the shorted reading from the same sensor that gives F12 when it reads open. The control treats a shorted sensor as untrustworthy and stops heating until the code is cleared.

SKS microwave display

What to do when F13 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.

## Before you book, in this order.

Each step comes from SKS's own guidance for F13 on its microwaves. Follow it to the end: the last card says whether this is a visit.

01

Press CLEAR/OFF to silence the unit and clear F13.

02

Let the cavity cool fully and try again with one function.

03

If F13 repeats, switch the unit off at the breaker and book a visit to test the sensor and its connection.

### 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

F13 is not an overheating warning, which appears as F6. It also says nothing about the turntable or the door; it is about one temperature reading.

## What you may notice with it.

The microwave problems F13 tends to arrive with. Answer these at the microwave before anyone is booked.

## Questions about F13.

### Can I clear F13 myself?

Press CLEAR/OFF to silence the unit and clear F13. If it comes back, it needs a visit.

### Is F13 on an SKS speed oven worse than F12?

Neither is more serious for you as the owner. Both mean the same sensor needs testing; only the kind of bad reading differs.

### Can I bake in my SKS speed oven if F13 clears after a reset?

If it clears and stays away, the unit can be used. Keep a note of when it appeared, because a code that comes and goes is easier to trace with that history.

### Will replacing the sensor on my SKS speed oven mean pulling it out of the cabinet?

Usually the unit has to come forward out of its opening for the technician to reach the sensor, which is why this is a visit and not a self-repair.
