How to fix surface burners that aren't heating properly on your Wards gas range
If neither the oven burners nor the surface burners heat properly, then check the gas supply going to the range for properly supply pressure. Get help from your local gas supplier if supply pressure is deficient. A failing pressure regulator in the range can also prevent oven and surface burners from getting the right amount of gas. You may need to replace the pressure regulator if the gas supply to the range is good but gas pressure going to the oven and surface burners is weak.
For an individual surface burner not heating properly, check for and clear any clogs from the burner orifice. A failed surface burner control valve can also prevent a surface burner from heating properly. Replace the burner control valve if it won't control gas flow properly.
Troubleshooting your Wards gas range when the oven won't heat
- Check the gas supply. If surface burners aren't working, check your gas supply cut-off valve to make sure it's open.
- Test the igniter. Pull the bottom oven panel out and start the oven. If the igniter glows but doesn't light the burner, it may not be getting hot enough to open the safety gas valve. You'll likely need to replace the igniter.
- If the igniter doesn't glow, measure resistance through the igniter using a multimeter. Replace the igniter if the meter measures infinite resistance.
- Test the safety gas valve. Measure resistance through the safety gas valve using the multimeter. The meter should measure less than 5 ohms of resistance through the gas valve. If the meter measure infinite resistance, you'll need to have a service technician replace the safety gas valve.
