It is possible that the valve itself simply wore out or was damaged due to leaks or submersions in the basement. Alternatively, one of the gas-igniting electronic components or a fault in the safety circuit may be the culprit. If your oven has a foot pilot light, the thermocouple could be worn out. If the gas valve is jammed or malfunctioning, the oven may close completely or simply stop supplying hot air.
There are other problems that can cause the same symptom, so you need an experienced technician to diagnose the problem and apply the appropriate repair. The problem may go beyond the gas valve, so several parts or repairs may be needed. This is an important indicator that something could be wrong with your oven's gas valve. A faulty gas valve can allow fuel to leak into the surrounding air.
A gas leak poses a safety hazard to your health and property, as a spark could cause a fire. If you notice a gas leak, you should leave your home immediately. Then contact a furnace repair and maintenance professional to assess the damage and offer a lasting solution. Connect your multimeter probes to the gas valve terminals.
If the reading is OL, then the gas valve is faulty. A faulty gas lighter is probably the most common failure of a gas oven. The igniter is an electrical component that ignites gas burners. Faulty igniter causes gas oven failure, but it's not expensive to replace.
At first glance, a gas oven may seem like a fairly simple configuration to diagnose and repair, however, it is actually a complex component for the entire system. For example, a natural draft furnace needs 100 CFM fan speed per 10,000 BTU input; a greater than 80% draft furnace needs 130 CFM per 10,000 BTU and a furnace greater than 90% needs 150 CFM per 10,000 BTU. Furnace gas valve opens and closes, allowing gas flow to pilot light and burners. In addition, the pilot safety valve only remains open if the thermocouple or thermopile is heated to a temperature determined by the pilot flame.
The gas valve manifold inside the oven opens and closes to allow the oven to burn gas and generate heat. If you think your oven gas valve isn't working, there are a couple of steps you can take to fix the problem and reduce the root cause. However, that could also indicate many other problems in the oven, so it's best to call a professional HVAC technician professional HVAC technician to be sure. In addition, it is important to check the thermostat wires to the oven if the thermostat has been replaced and still does not turn on.
First of all, as a technician, you need to know the sequence of events that occur in order for a gas furnace to start properly. If your gas valve is faulty but you don't think there is a gas leak, prompt service is still important. To troubleshoot a furnace gas valve, the first thing you need to check is the oven operation sequence. If the pressure of the gas entering the burners were too high, the burner flames would be too large and the oven could overheat.
Only the gas valve manufacturer or someone certified by the gas valve manufacturer can perform these repairs. When it comes to troubleshooting a furnace gas valve, there is also a low fire setting on two-stage units that needs to be checked. While the component itself is quite simple, a furnace gas valve is a crucial part of your HVAC system. A transformer in a gas oven is essential, as it increases or decreases the electrical voltage as it travels from the circuit board to the HVAC unit.
