Possible Causes
Weak or failing heating element, thermostat opening at too low a temperature, poor contact between warming plate and thermostat, heavy scale reducing heat transfer
How to Fix / Troubleshooting
Safety first: Unplug and allow the plate to cool before touching or disassembling.
Check settings:
- Some Black+Decker models have adjustable keep warm settings; ensure it is set to HIGH or default.
Measure performance:
- Brew a full pot and measure coffee temperature immediately; typical should be around 175–185°F (80–85°C).
Internal inspection:
- Remove the bottom cover to access the warming plate heater and thermostat.
- Check for loose mounting of the thermostat; it must be firmly pressed against the plate.
- Descale the heating tube to improve heat transfer.
When to replace:
- Replace a weak or open heating element if it does not reach proper temperature.
- Replace a thermostat that opens too early or is out of specification with a correct-temperature warming plate thermostat.
