Gas Oven Repair Tips
Is your oven not baking?
- Bad bake ignitor. You can't tell it's bad by looking at it--you must measure amperage. Just because it glows orange, doesn't mean it's good. On round ignitors, look for a current draw of 2.6 to 2.8 amps. On flat ignitors, look for 3.2 to 3.6 amps. Insufficient current draw will not allow the gas valve to open. If unsure how to test, check this tech sheet.
- Bad valve. If ignitor checks out OK, remove power from oven, pull the two wires off the valve and ohm test. Should read two to five ohms. If open, replace valve.
- Pilot is out. Try reigniting pilot. If it goes out again, check 1) gas supply (out of gas, crimped line, etc.), 2) pilot orifice clogged or dirty.
- Pilot flame not wrapping around thermocouple. Reposition the thermocouple bulb so the pilot flame wraps around it.
- If pilot is spark ignited and you're not getting spark to the pilot, replace the spark electrode, spark module, and the ignition wire. These parts are inexpensive enough that it's not worth the trouble to just replace one, replace the entire ignition system as long as you're in there.
- If your broiler is not working check the above steps with the broiler instead of the oven
Is your oven not self-cleaning?
- Self clean latch bent or misaligned. Inspect for proper alignment to make sure that latch is contacting the latch switch.
- Defective Self clean latch switch. Run continuity check.
- Bad function selector switch. Run continuity check on switch.
Is your gas oven not getting hot enough?
- Sluggish ignitor. A good ignitor will fire the oven in less than three minutes. If it takes longer than this, the ignitor is starting to go. Measure ignitor current draw as described above. As the ignitor gets sluggish, it takes longer for it to fire the burner as the oven cycles on and off while the in use thus lowering operating temperature.
- Oven door gasket ripped or torn.
Is your oven door stuck closed?
- Defective ERC. Check for error code in display. If error code given, check against manufacturer's code explanations in owner's manual or tech data sheet inside oven control panel.
- Misaligned self clean latch. Disassemble oven to manually free latch and realign or replace as needed.
