What are common reasons a Bunn coffee maker may not heat up?
The most common reasons for a Bunn coffee maker not heating up include a faulty power source, issues with the internal thermostat, or a malfunctioning heating element. If your brewer isn’t plugged in properly or there’s a problem with the outlet, the machine won’t receive the electricity it needs to heat water.
