Pilot Burner Won’t Light

If the gas supply is on but the pilot burner doesn’t light, check for the following problems:

  • Obstruction in gas supply – Double check that all manual gas valves are open. If they are, look for blockages in the gas supply tubes and pilot burner orifice. Remove any obstructions that could affect gas flow. If gas pressure in your facility is low, contact your local gas company to help correct the issue.
  • Poor electrical connection on gas control – See if there is a bad electrical connection between the module and pilot operator. Have an authorized Garland technician or service company check or repair this problem.

Sparking When Pilot is Lit

When sparks don’t stop when the pilot is lit, look for the issues below:

  • Dirty or damaged flame rod – Whenever the flame rod is dirty, this can obstruct the burner from lighting. Make sure to clean the flame rod and surrounding area. If you notice a crack in the rod’s ceramic insulator, have it replaced by an authorized technician.
  • Bad electrical connection – Check if there is a poor electrical connection between the model and flame rod. Have the issue checked and corrected by an authorized technician.
  • Poor flame – The pilot flame could be out of adjustment and might need to be modified accordingly. It should be covering the rod and maintain a steady blue flame.

Main Burner Won’t Light

Look for electrical connections between the gas control and module. If they’re okay, make sure an authorized technician repairs or replaces the gas control or control operator.

Fan Won’t Run

Here are some potential problems that keep the oven’s fan from running:

  • No power – Before diving into the unit, see if the oven’s power is off. Check if it’s unplugged or turned off or if there is a tripped circuit.
  • No power from relay board – Have an authorized technician see if there is proper voltage from the relay board to the motor.
  • Open micro switch – Have an authorized technician see if the micro switch won’t close.

Poor Pilot Flames

When you notice the issues below, contact an authorized technician or service company to make necessary repairs:

  • Small blue flame – This usually tied to lack of gas to unit. Look for clogs in either the orifice or pilot filter, and clean it out to help more gas flow out. If neither are clogged, check if there is low gas supply pressure to the oven. You might need to contact a local gas company to remedy the issue.
  • Weak yellow flame – This type of flame normally comes from lack of air. See if either the lint screen or primary air opening is dirty. Cleaning them out should help make the flame stronger. If not, a large orifice also could be contributing to a weak yellow flame.
  • Waving blue flame – Extreme draft near the pilot or recirculating products of combustion could be causing the wavy flame.
  • Noisy blowing flame – High gas pressure could be contributing to this problem. You might need to have your local gas company adjust the pressure to the facility accordingly.
  • Sharp flame – The orifice could be too small or gas pressure is too high.
