Hotpoint Oven Error Code F3
Oven RTD sensor open
Common Causes
- 1RTD probe failed open
- 2Rear sensor plug backed off
- 3Conductor snapped in the probe lead
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.
Step-by-Step Troubleshooting
- 1
Get behind the range and find the oven sensor plug where it exits the rear wall
- 2
Push the plug firmly back together — a connector shaken loose is the most common trigger here
- 3
Ohm the probe and expect roughly eleven hundred ohms at room temperature
- 4
An open or OL reading condemns the probe, so fit a fresh RTD
Pro Diagnostic Tip
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.
