Frequently Asked Questions

Q: Why is hot air blowing from the top of the oven door?

A: This is normal. The oven has a cooling fan that helps maintain precise internal temperatures. The fan vents through the top of the oven door and behind the cooktop.

Q: Why does the oven fan keep running after I turn the oven off?

A: The fan continues to run after the oven is turned off until the internal temperature has cooled sufficiently. This is normal operation.

Q: My burner is sparking or clicking but won’t ignite. What should I do?

A: First, check for a gas smell. If there is no smell, there may be air in the line—repeat the proper lighting procedure several times. If you do smell gas, follow safety procedures and continue troubleshooting carefully.

Q: My burner is producing black soot. What causes this?

A: Black soot is usually caused by an improper propane mixture or conversion. Ensure the unit is correctly converted for LP gas and that the gas source is appropriate. For natural gas units, check that the home’s gas pressure is within 6″ to 14″ water column.

Q: I smell gas. What should I do?

A: Do not operate the range. Immediately follow safety precautions. If using LP gas, make sure the unit was properly converted by a qualified technician.
