Overheating or too hot

The PCB assembly is designed to be reliable and should not be replaced based on guesswork. Follow the complete trouble diagnosis procedure before concluding that the PCB is faulty. The manual explicitly warns against replacing the PCB assembly by wrong diagnosis. Every diagnostic flowchart ends with 'The problem is in the PCB assembly. Please replace it.' only after all other checks pass.

When reassembling the Drum Wrapper (for both electric and gas models), check the welding line mark on the Assy Drum Wrapper assembly right side. Incorrect orientation of the drum wrapper during reassembly can cause an out-of-round condition leading to thumping noise and a high weld seam that contacts the bulkhead seals.

For gas dryers, the 120V wall outlet must be properly polarized AND grounded. The larger slot must be neutral, the smaller slot must be hot (live), and the round hole must be connected to ground. A mispolarized outlet (larger slot is hot, smaller slot is neutral) or an ungrounded outlet can cause erratic operation, safety issues, and potential electric shock. Use a circuit analyzer or multimeter to verify: 115±15 VAC hot to neutral, 115±12 VAC hot to ground, 0 VAC neutral to ground.

AC220-240V is applied to the triac T1 and T2 on the main PCB. Even when the dryer appears off, dangerous voltage may be present on the PCB. Strong and weak electricity are mixed together on the board. Never touch PCB components while the dryer is plugged in.
