How to Fix / Troubleshooting
Safety first: Unplug and allow the unit to cool before inspection.
- Step 1 – Check cord and plug: Wiggle the cord gently at the plug and where it enters the unit (while unplugged). Look for looseness or damage.
- Step 2 – Improve ventilation: Ensure the unit is not enclosed or too close to walls or cabinets.
- Step 3 – Observe timing: If shutdown occurs after a consistent time at high temperature, a thermal device may be tripping.
- Step 4 – Internal inspection (advanced): Open the housing and inspect the control board and thermal devices for discoloration or loose connections.
- Step 5 – Professional repair: Replace any suspect thermal cutoffs or the control board if overheating damage is visible.
