Common Issues With Electric Heaters And How To Fix Them

The importance of electric heaters during winters cannot be overemphasized. However, like any other appliance, heaters experience technical problems that hinder their normal operations. The most common issue faced with heaters is blowing cold air instead of hot air.

In this article, we will discuss all the possible reasons why your heater is not blowing out hot air and what you can do to correct the problem.

Why Your Heater May Fail To Blow Out Hot Air

  1. An Incorrectly Set Thermostat

If a thermostat is incorrectly set, it will affect the heating operations of your heater. For instance, if it is set to ON, the blower motor will run continuously even when the air passing over the coil is not heated. To fix this, simply set the thermostat mode to AUTO.

  1. Broken and Leaking Ducts

An old or unmaintained piping system can significantly contribute to the heater’s cold air blowing issue. In this case, you must contact a heater service professional to ensure that your ductwork is in good health to avoid the issue.

  1. Dirty and Clogged Air Filters

A dirty air filter hinders the airflow over the heat exchanger, resulting in an excessively hot exchanger that shuts down automatically to prevent thermal damages. To fix this, either clean the air filter or hire a technician to do the cleaning for you.


As discussed earlier, these are some of the many different reasons that can force your heater to blow out cold air. You can follow the recommendations provided to avoid/fix these issues, or if your system needs a professional Maintenance, then please feel free to contact ProServices Supply on (877) 776-8228, and one of their technicians will come to look after the heater for you.
