Possible Causes
Open heating element, Burned heater connector, Failed heater relay or triac on main control PCB, Broken high-temperature wiring to heater
How to Fix / Troubleshooting
Safety first: Unplug and allow the unit to cool before accessing internal parts.
Steps to diagnose no heat:
- Visual check: Look at the heating element through the top. If it never glows red at high temperature, suspect the heater circuit.
- Access heater terminals: Remove the top cover to reach the heating element assembly. Inspect for burned or loose connectors.
- Continuity test: Measure resistance across the heater terminals. An open circuit indicates a failed element.
- Check wiring: Follow the high-temperature wires from the heater to the relay/triac on the main control PCB. Look for breaks or heat damage.
- Replace components: Replace a failed heating element assembly or, if the element is good but not powered, replace the main control PCB that drives it.
