When a system issue occurs, Honeycomb Heating & Cooling offers local heater repairs to restore its efficiency.

We understand the frustration that comes with a heater that won’t turn on or that operates inadequately. We’re here to help you identify a few issues that could be causing the problem. Read ahead to learn about common heating concerns and how you can troubleshoot furnace issues before calling in a professional from our team.

Common Causes Of Heater Problems

Your home’s heating system is made up of many components that work together to keep you warm. When one of these parts malfunctions, it can cause your system to stop working.
Honeycomb is here to share some of the most frequent reasons homeowners experience heating issues.

1. Incorrect Thermostat Settings

One of the first things to check when your unit won’t turn on is the thermostat. If it’s not set correctly, your heater won’t receive the signal to start.

Check that the thermostat is in “heat” mode. Ensure the system temperature is set above the current room temperature. In some cases, dead batteries or wiring problems can prevent the thermostat from functioning properly.

2. Pilot Light Or Ignition Problems

If your furnace doesn’t ignite, you could be dealing with a problem related to the pilot light or ignition system. Older systems rely on a pilot light to ignite the burners. If this component goes out, your furnace won’t produce heat. Modern systems often use an electric ignition system, which can malfunction due to electrical issues or faulty components.

3. Dirty Or Clogged Filters

Your system’s air filter plays a critical role in ensuring proper airflow. Over time, dust, dirt and debris can lodge in the filter. When this happens, it restricts airflow and can cause the system to operate inefficiently. Replacing your air filter every 1–3 months can help prevent this problem.

4. Tripped Circuit Breaker Or Blown Fuse

Sometimes, the solution to your heating problem is as simple as checking your electrical system. If your heater doesn’t turn on, a tripped circuit breaker or fuse issue may be the cause of the issue. Head to your home’s electrical panel and look for any breakers that have been tripped. Resetting the breaker might solve the problem.

5. Faulty Blower Motor

ir throughout your home. If the motor is damaged or malfunctioning, your heating system may turn on, but it won’t be able to blow warm air into your living spaces.

You might hear the unit running, but with little to no airflow, it won’t do much to heat your home.

What To Do If Your Heater Won’t Turn On

If your furnace is not kicking on or experiencing any of the issues listed above, here are a few steps you can take before calling a professional:

• Check the thermostat — Ensure it’s set to the correct mode and temperature.
• Inspect the air filter — If it’s clogged, replace it with a clean one.
• Reset the circuit breaker — If the breaker controlling your unit has tripped, try resetting it.
• Check the pilot light — If the flame is out, relight it following your manufacturer’s instructions.

While these troubleshooting tips may help, it’s essential to contact our local HVAC technicians if the problem persists. Attempting DIY repairs on a malfunctioning system can lead to additional damage or safety risks.
