Gas dryer valves are a critical part of the appliance’s operation. They open and close to allow gas to flow to the burner, which heats the air that dries your clothes. If the valve fails, the dryer will not be able to heat properly. In this article, we will show you how to test a gas valve coil on a dryer. This is a simple process that can be completed in a few minutes.
**Before you begin,** make sure that the dryer is disconnected from the power supply. You will also need a multimeter, which is a device used to measure electrical current. Once you have gathered your materials, follow these steps:
1. **Locate the gas valve.** It is usually located on the back of the dryer, near the burner.
2. **Disconnect the wires from the gas valve coil.** There are usually two wires, one black and one white.
3. **Set your multimeter to the ohms setting.**
4. **Touch the probes of the multimeter to the terminals of the gas valve coil.** The reading should be between 200 and 1000 ohms.
5. **If the reading is not within this range,** the gas valve coil is defective and needs to be replaced.
How to Test Gas Valve Coils on a Dryer
If your dryer is not heating, one of the possible causes could be a faulty gas valve coil. Testing the gas valve coils is a relatively simple task that can be done with a multimeter. Follow these steps to test the gas valve coils on your dryer:
- Unplug the dryer from the power outlet.
- Remove the access panel to the dryer’s gas valve.
- Locate the gas valve coils. There should be two coils, one for the main burner and one for the pilot light.
- Disconnect the wires from the gas valve coils.
- Set your multimeter to the ohms setting.
- Touch one probe of the multimeter to each terminal on the gas valve coil. The multimeter should read between 100 and 200 ohms.
- If the multimeter reads 0 ohms, the gas valve coil is shorted and needs to be replaced.
- If the multimeter reads infinity, the gas valve coil is open and needs to be replaced.
