Why Is My Heating Not Coming On

Why is My heating not coming On ? Check 8 Step

A functioning heating system is essential for maintaining a comfortable and cozy environment in your home. However, there may be instances when your heating system fails to come on, leaving you feeling cold and frustrated. In this guide, we will explore some common reasons why your heating may not be coming on and suggest troubleshooting steps to help you identify and potentially resolve the issue.

Check the Thermostat

Ensure the thermostat is set to the desired temperature and mode (heating). Make sure the thermostat has power and the batteries, if applicable, are not depleted. Adjust the temperature higher than the current room temperature to see if the heating system responds.

Power Supply

Verify that the heating system has power. Check the circuit breaker or fuse box to ensure the circuit for the heating system is not tripped or the fuse is not blown. If it is, reset the circuit breaker or replace the fuse.

Pilot Light or Ignition

If you have a gas heating system, check if the pilot light is lit. If the pilot light is out, follow the manufacturer’s instructions to relight it. For newer systems with electronic ignition, listen for the sound of the ignition system. If you don’t hear a clicking sound, there may be an issue with the ignition system that requires professional assistance.

Fuel Supply

If you have an oil or gas heating system, ensure that there is an adequate supply of fuel. Check the fuel levels and arrange for a refill if necessary. If you suspect a fuel delivery issue, contact your fuel supplier for assistance.

Airflow and Vents

Check all heating vents and registers to ensure they are open and not blocked by furniture, rugs, or other obstructions. Restricted airflow can prevent the heating system from distributing warm air effectively. Also, inspect the air filter and clean or replace it if it’s dirty or clogged.

Pressure or Water Level

For a hydronic heating system, such as a boiler, check the pressure gauge or water level indicator. Low pressure or water level can cause the system to shut off. If needed, follow the manufacturer’s instructions to adjust the pressure or water level.

System Malfunction

If none of the above steps resolve the issue, there may be a malfunction or fault within the heating system itself. In such cases, it’s advisable to contact a qualified heating technician or engineer to diagnose and repair the problem.


Experiencing a heating system that won’t come on can be frustrating, especially during cold weather. By following the troubleshooting steps outlined above, you can identify potential causes and resolve minor issues on your own. However, if you are unsure or unable to resolve the problem, it’s always recommended to seek professional assistance to ensure the safe and proper functioning of your heating system.
