What is the Hotpoint Oven F3 error?#
F3 on a Hotpoint oven means the oven RTD sensor read open: the temperature probe circuit is broken, so the oven puts out no heat while the display may still show a temperature. It is not a safety hazard the way an overheat code is, and the most common trigger is simply the rear sensor plug backing off — so reseating that connector is the first thing to check.
F3 on a Hotpoint Oven: likely causes and repair cost#
On a Hotpoint Oven, the F3 code signals: oven rtd sensor open.
| Likely cause | Typical likelihood |
|---|---|
| RTD probe failed open | Most common |
| Rear sensor plug backed off | Common |
| Conductor snapped in the probe lead | Less common |
Typical professional repair: $50–$150 · Difficulty: moderate · often owner-fixable
Symptoms that often accompany F3: The oven putting out no heat at all; A temperature on the display while the cavity stays cold; The fault surfacing during a self-clean
Technician diagnostic sequence for F3:
- Get behind the range and find the oven sensor plug where it exits the rear wall
- Push the plug firmly back together — a connector shaken loose is the most common trigger here
- Ohm the probe and expect roughly eleven hundred ohms at room temperature
- An open or OL reading condemns the probe, so fit a fresh RTD
Parts a technician may check or replace: oven temperature sensor
Field note: The open reading here is the mirror of a shorted probe; when the two codes swap back and forth run to run, the trouble is an intermittent break in the lead. Flex the harness while you watch the meter and the reading will jump at the fracture point.
Safety note: Self-clean bakes the probe past nine hundred degrees. A code that first shows during or after a clean usually means the probe fatigued from that heat.

How to troubleshoot the F3 error yourself#
F3 is one of the more owner-approachable oven codes because the most common cause is a loose connection. Get behind the range and find the oven sensor plug where it exits the rear wall, then push the plug firmly back together — a connector shaken loose over time is the most common trigger, and reseating it clears many F3 faults for free. If reseating does not fix it, the probe itself is likely open: an RTD sensor reads roughly eleven hundred ohms at room temperature, and an open or OL reading condemns it. Testing the probe with a meter and fitting a fresh RTD is a manageable repair but still a technician-level task involving the rear of the range. Two useful clues to note: F3 is the mirror of a shorted-probe code, so if the two swap back and forth run to run, the trouble is an intermittent break in the lead rather than a dead probe — flexing the harness while watching the meter makes the reading jump at the fracture point. And if F3 first showed during or after a self-clean, the probe likely fatigued from the extreme self-clean heat. Reseat the plug yourself, and if the probe is genuinely open, let a technician replace it.
Is the Hotpoint Oven F3 error worth fixing?#
F3 is very much worth repairing and is the cheapest oven fault in this set. It is frequently free, since a backed-off rear plug just needs reseating; when the probe has genuinely failed, the professional range is only $50 to $150 — an oven temperature sensor and labor. Against a comparable new range that is trivial, and a sensor fault says nothing about the bake or broil elements or the control board. There is no scenario where F3 alone justifies replacing the oven — reseat the connector, and if the RTD is open, an inexpensive probe restores full heating.

Hotpoint Oven F3: frequently asked questions#
What does F3 mean on a Hotpoint oven?#
It means the oven RTD temperature sensor read open: the probe circuit is broken, so the oven produces no heat while the display may still show a temperature.
Is it safe to keep using an oven showing F3?#
There is no overheat hazard — the oven simply will not heat. It is fine to leave it until repair, but it will not cook until the sensor circuit is restored.
Can I clear F3 myself?#
Often, yes. Reseating the oven sensor plug at the rear of the range fixes many F3 cases at no cost. If the probe itself is open, a technician replaces the inexpensive RTD.
How much does it cost to repair F3?#
Frequently nothing when a reseated plug fixes it. When the RTD probe must be replaced, a professional repair runs $50 to $150.
Why did F3 appear after a self-clean?#
Self-clean drives the probe past extreme temperatures, and a marginal RTD can fatigue and open from that heat. A code that first shows during or after a clean usually means the probe failed then.
Is a Hotpoint oven with F3 worth repairing?#
Yes — it is often free (a reseat) or at most a $50–$150 sensor repair, so there is never a reason to replace the oven over F3.
