Most Frequent Causes for Heater overheating:
- Check the Output from Your Circuit Breaker Panel to Your Heater
With the help of a screwdriver, carefully uncover the circuit breakers panel box. Then, get your volt ohmmeter to the volts position after turning it on. The red lead and the black lead should be placed into the “Volts” connector and the “common connector,” respectively. Once this is done, the breaker should be switched on to the baseboard heater.
The red lead should be touched to a terminal screw that is at the bottom of the circuit breaker. Ensure that the reading on your meter is 220 Volts. If no, it means that your breaker needs to be replaced. If yes, then simply move to the next step.
- Check Your Thermostat
The panel cover can be replaced once the breaker is turned off. Uncover the electrical cover of the baseboard heater and check that there are two wires connected to the thermostat switch.
- Check for Resistance
We need to ensure that the meter is in the ohms position. There is a connector at one end of the heater that needs to touch one lead of the meter. The other end of the heater is where the other lead should be placed. There should be some kind of resistance reading shown on the meter. You will know that the heater element of the baseboard is burnt out if your meter shows as wide-open or infinite Ohms. If the heater shows as OK, you can safely move to the next step.
- Check the Feed Wires
Replace the red lead in its original position, i.e., in the “Volts connector” and also ensure that the meter is back in the “Volts position.” The circuit breaker should then be switched on. Follow the instructions for checking your thermostat, wherein the leads of the meter are touched to the heater element. Ensure that the meter reading shows as 220 Volts. The feed wires need to be replaced if the meter reading is less than 110 Volts. Check the wires backward to find a break or simply replace them.
