Signs Your Garage Heater Needs Repair

Some garage heater problems are obvious, and others build slowly until the garage just never gets warm. Watch for these warning signs:

• No heat at all: The thermostat calls for heat, but the burner never lights.
• Fan runs, air stays cold: The blower comes on and pushes air, but it isn’t warm.
• Short cycling: The heater fires, runs for a minute or two, then shuts down and tries again.
• Strange noises: Rattling, squealing, or loud clicking points to a worn motor, loose part, or ignition trouble.
• Odd smells: A lingering burning or gas smell means you should shut the heater off and have it checked right away.
• Rising gas bills: A heater that runs longer to keep the same temperature may have a dirty burner or a control problem.

Any of these can come from several different causes, which is why testing beats guessing at parts.

How We Diagnose and Fix Garage Heaters

When a heater won’t kick on or blows cold air, the cause is usually somewhere in the ignition and safety chain that has to work in order before the burner lights. We test each step so you only pay to replace what’s failed.

Common Garage Heater Repairs

The most common no-heat failures we find are a worn igniter or a dirty flame sensor that can’t prove the burner lit, so the gas valve shuts off for safety. Other frequent repairs include failed inducer or blower motors, stuck pressure switches, tripped limit switches from blocked airflow, faulty gas valves, and thermostat or wiring problems. Repair cost depends on which part failed, the heater’s age, and how easy the unit is to reach on the ceiling, and we’ll go over the price before any work starts.

Before you schedule, it’s worth checking a few simple things. Make sure the thermostat is set to heat and above the garage temperature, the heater’s power switch and breaker are on, and the gas valve to the unit is open. If those check out and the heater still won’t run, it’s time for a technician.
