Heater Not Igniting

One common issue is the heater not igniting. This can be frustrating. Check the power supply first. Ensure the heater is plugged in correctly. Inspect the circuit breaker. It might have tripped. Reset it if needed. Examine the gas supply. Make sure the valve is open. If there is no gas flow, the heater won’t ignite. Also, look at the igniter. It might be dirty or broken. Clean it carefully.

Gas Line

Next, inspect the gas line. Make sure the gas valve is open. The heater won’t work if the gas is off. Check for any gas leaks. Use a soapy water solution to identify leaks. Bubbles indicate a leak.
