Why your heater isn't warming: 5 common causes and what to do

If your heater has stopped warming, don't rush to throw it away — in most cases the issue is fixable. Let's look at the main causes.

1. Faulty heating element

The heating element is the most common culprit. Over time it burns out, especially with unstable voltage. Replacement takes up to an hour.

2. Thermostat failure

If the heater doesn't respond to temperature changes or won't switch on, the thermostat may be to blame.

3. Wiring problems

Oxidised contacts or a damaged cable cause a loss of heat and can be dangerous.

4. Overheat protection tripped

Modern models have a thermal fuse that shuts the device off when it overheats.

5. Power supply issues

Low voltage or a faulty circuit breaker also affect operation.
