Possible Causes
Burned-out bottom heating element, Disconnected heater wiring spade terminals, Tripped thermal fuse in series with heater, Faulty heater relay on control PCB
How to Fix / Troubleshooting
Safety: Unplug the cooker and ensure it is cool before removing the bottom cover.
- Visual inspection: Turn the unit upside down on a soft surface. Remove the base screws and bottom cover. Locate the circular heating element under the inner pot area.
- Check wiring: Inspect the heater terminals and wires. Ensure spade connectors are tight and not burnt. Reseat any loose connectors.
- Continuity test (advanced): Using a multimeter set to ohms, measure resistance across the heater terminals. A typical reading is between 20–60 Ω. Infinite resistance indicates a failed element that must be replaced.
- Inspect thermal fuse: Look for an inline thermal fuse attached to the heater or wiring harness. Test for continuity; if open, replace with the same temperature and current rating.
- Board-level issues: If the heater and fuse test good, the heater relay or triac on the control PCB may be defective. Replace the control PCB or seek professional repair.
