Gas Valve Troubleshooting | Diagnosis and Repair
Gas Valve Troubleshooting - Gas valves used in modern state-of-the-art residential gas furnaces are typically controlled via a state-of-the-art electronic ignition control or a printed circuit board. Other types of gas valves include the standing pilot gas valve.
Gas valves can be found on gas furnaces, gas-fired steam boilers or hot water boilers, and gas-fired water heaters. With gas valve troubleshooting and any “gas valve” issues, safety is always first.
When troubleshooting a gas valve, the technician should only be concerned with input to the gas valve and output of the gas valve, whether it is an electronic module or circuit board controlled gas valve, or a standing pilot gas valve. The input with gas valve troubleshooting includes ensuring the safety circuit is good.
