Possible Causes
Stuck heater relay on control board, Incorrect auto-off setting, Thermostat welded closed, Firmware error
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker when not in use to prevent overheating or fire risk.
- Check auto-off setting: Some Insignia models allow adjusting the keep-warm duration. Set it to the minimum and test.
- Observe behavior: Time how long the plate stays hot after brewing. If it exceeds the specified auto-off time, discontinue unattended use.
- Internal inspection (advanced): With the base removed (unplugged), inspect the control board relay controlling the plate for signs of heat damage.
A warming plate that never turns off indicates a control or thermostat failure and should be serviced or the unit replaced.
