Error Code: E66 Difficulty: Hard
Problem: Thermal limiter tripped.
How to Fix E66 Error (Step-by-Step)
- Unplug the dryer from the power source for safety and confirm the error stays cleared during a full test cycle.
- Inspect the dryer’s venting system for any lint buildup or obstructions and clean it thoroughly.
- Locate the thermal limiter, which is a small, non-resettable fuse on the heater housing.
- Disconnect the wires from the thermal limiter and test it for continuity with a multimeter.
- If the multimeter shows no continuity, the thermal limiter has blown and must be replaced.
- Replace the faulty thermal limiter with a new one and confirm the error stays cleared during a full test cycle.
- Reassemble the dryer and test to ensure it heats properly.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
