Gas Heater not Working

If your gas heater is not working, there could be a number of possible causes. One common issue is a lack of gas flow, which can occur if the gas valve is turned off or if there is a problem with the gas supply. Another potential cause could be a malfunctioning thermocouple or ignition system, which can prevent the heater from starting properly.

If you are experiencing problems with your gas heater, it is important to first ensure that the gas supply is turned on and that there are no issues with the gas line. If these basic checks do not resolve the issue, it may be necessary to call a professional heating technician to diagnose and repair the problem. Regular maintenance and cleaning can also help to prevent issues with gas heaters and ensure that they are working safely and efficiently.
