Kenmore Dryer Error Code F23
Exhaust sensor reading a dead short
Common Causes
- 1Sensor bead shorted internally
- 2Bare conductor touching the dryer frame
- 3Moisture bridging the sensor plug
Step-by-Step Troubleshooting
- 1
Read the outlet bead cold — a dead short falls near zero, where a healthy sensor should sit up around ten thousand ohms
- 2
Unplug the bead and read it alone; a normal reading detached means the harness is grounding out somewhere
- 3
Hunt for a pinched lead near the heater housing where radiant heat crazes insulation and bares the copper
- 4
Dry any dampness across the plug, then renew the bead or splice the loom as the isolation test directs
Pro Diagnostic Tip
On the Whirlpool-platform 110-series Kenmore, a shorted exhaust thermistor feeds the board a false cold reading, so it keeps the heat on and the drum runs far too hot. Treat it as urgent — chronic overheating cooks the thermal fuse and can scorch a load, so replace the sensor before running another cycle.
You Might Also Notice
- •The drum runs blisteringly hot
- •Loads come out overdried or singed
- •The thermal fuse keeps blowing out
