This Fix-It Guide on gas oven repair tells how a gas oven works, what can goes incorrect, how to identify a gas oven problem, and what parts and tools you will need to fix information technology. It and then gives simple pace-by-pace instructions for how to re-light an oven pilot, how to clean a gas oven burner, how to conform an oven flame, how to bank check and replace a gas oven spark igniter, how to check and supervene upon a glow bar, how to service an oven door, how to supervene upon oven gaskets, and how to replace gas oven door-mounted gaskets.

How Does a Gas Oven Work?

Gas Oven Repair

Components of a typical gas oven and cooktop.

A gas oven is the blistering chamber fueled past natural or propane gas. Some gas ovens have a airplane pilot low-cal that stays lit all the fourth dimension, igniting the burners as needed. Newer models have spark igniters or an electrically heated curl, called a glow bar or glow plug to ignite the gas on need. Igniters are wired to an ignition module that produces the high voltage required for sparking. A thermostat controls oven temperature past regulating the gas supply to the oven. If you're having trouble with the cooktop attached to your gas oven, run into the Gas Cooktop Ready-It Guide .

What Can Go Wrong with a Gas Oven?

The pilot light may go out. The burner ports may need clearing. The igniter and ignition module tin can malfunction. The fuse and glow bar (if equipped) can neglect. The door may need adjusting and gaskets may demand replacing. The thermostat or capillary tube may be faulty. The pilot may need adjusting. The burner flame may need adjusting.

Caution!

Make sure you know how to shut off the gas to your oven for repairs and in case of emergency.

How Can I Identify a Gas Oven Trouble?

  • If the oven burner doesn't light and information technology has an electrical igniter, make sure that the range is plugged in and that in that location is power from the electrical service panel. R-elight or suit the airplane pilot (see below), clear the burner ports (meet below), and inspect the igniter and ignition module on ovens with electric igniters (see below). Also test the Fuse (beneath the oven bottom and baffle, side by side to the prophylactic valve) and glow bar on ovens with glow bar igniters (see below).
  • If the oven burner pilot doesn't stay lit, clear the airplane pilot opening (see below) and adjust the airplane pilot (run across below).
  • If the oven doesn't work at the set temperature or the oven bakes unevenly, cheque the door (see below) and gasket (run into below); articulate the burner ports (see beneath); or call for service on a thermostat or capillary tube.
  • If the self-cleaning wheel of an oven doesn't work, check the owner's manual for instructions. So check the door (encounter below) and gaskets (see below), or phone call for service on a thermostat or capillary tube, every bit needed.

Caution!

Self-cleaning ovens often have a capillary tube that contains a caustic fluid. Wear rubber gloves and handle information technology gently.

Newer gas ovens may take digital controls that aren't serviceable past the consumer. Cheque the owner's manual for troubleshooting tips and how to get plug-in replacement parts as needed. Some units likewise have diagnostic tests and error codes that tell you what'due south incorrect with the unit.

What Are the Steps to Gas Oven Repair?

Fix-It Tip

Any repairs that involve the gas supply lines should be handled past a professional person service technician.

Relight a gas oven airplane pilot:

  1. Plow all controls OFF, open up the doors, and allow gas to dissipate.
  2. Concur a lighted lucifer nigh the tip of the pilot on the burner assembly. If a burner does non low-cal within two minutes, adjust the pilot, footstep 3.
  3. Turn the pilot adjustment screw (located near the pilot or the thermostat) in small increments and retest until the pilot has a blue flame.

Clean a gas oven burner:

  1. Turn all the apparatus controls to OFF.
  2. Remove the oven bottom (typically held in place past tabs or fasteners).
  3. Remove the baffle beneath the oven bottom.
  4. Turn on the oven and watch the burner. If the flame is not continuous along the length of the burner, some flame ports may exist clogged. Turn off the oven and let the burner cool, then articulate each port in the burner with a sewing needle.

Ready-It Tip

What should a well-adjusted gas oven flame await like? It should be blue in color, symmetrically shaped, and about 1/2 inch alpine. A ragged, hissing flame indicates too much air. A xanthous orangish flame indicates too fiddling air. Earlier adjusting, make sure the oven is turned off and cool.

Adjust a gas oven flame:

  1. Turn all of the appliance controls to OFF. Open the door and remove the oven bottom and bamboozle (see above).
  2. Plough on the oven and inspect the flame.
  3. Identify the air shutter that volition be adjusted. It may be at the base of the oven burner, just above the safety valve, or somewhere along the gas commitment tube.
  4. Loosen the setscrew that locks the shutter or plate, and adjust the opening to increment or subtract the amount of air mixing with the gas.
  5. Turn the oven on again to verify the adjustment, repeating as needed.
  6. Once the flame is correctly adapted, plow off the oven and tighten the setscrew.

Check and supplant a gas oven spark igniter:

  1. Turn all of the appliance controls to OFF.
  2. Open the door and remove the oven bottom and the bamboozle (see above).
  3. Unscrew the igniter from its mounting bracket and inspect it for cracks or other defects. Supersede it if it is damaged.
  4. To supplant a faulty igniter, find the ignition command module, unscrew the cover, and disconnect the module. Install the replacement part and test.

Cheque and replace a gas oven glow bar:

  1. Turn on the thermostat.
  2. Plow off power to the appliance.
  3. Unscrew the cover plate over the glow bar ring at the dorsum of the range and disconnect the plugs, or detect the glow bar below the oven baffle.
  4. Set a multimeter to RX1 (resistance times 1) and touch a probe to each glow bar last. Replace the glow bar if it does not show continuity. If the glow bar has continuity, the safety valve may be faulty, requiring professional service.
  5. Replace a faulty glow bar by unscrewing it from the burner support bracket and the oven wall, then pulling the glow bar free of the terminal block.
  6. Mount the replacement glow bar in the burner back up bracket, reconnect its plugs, and replace the metal cover.

Service a gas oven door:

  1. To fix a cocked door, open the door and loosen the screws securing the inner panel. Hold the door at the superlative and twist it from side to side to seat it securely on its hinges.
  2. Partially tighten the door screws; do not over-tighten screws on a porcelain door because you might chip the surface.
  3. Test the seal by inserting a piece of paper between the seal and the top corners of the oven. The seal should tightly grip the paper.
  4. To replace cabinet-mounted springs, remove the storage drawer and the door. Unhook and replace the springs. Supervene upon both springs even if but one is broken.

Replace gas oven gaskets:

  1. Unplug the oven or shut off power at the electric service panel, shut off gas to the oven, and pull the oven away from the wall.
  2. Remove the gaskets by unscrewing or un-clipping retainers.
  3. Locate and loosen the oven liner bolts from the back of the unit.
  4. Partially remove the oven liner by rocking information technology back and along. Disconnect the gasket from between the liner and the chiffonier.
  5. Place the new gasket behind the oven liner rim.
  6. Reinstall the oven liner and reattach information technology to the back of the oven.

Fix-Information technology Tip

On cocky-cleaning ovens, the gasket is held between the panels of the oven door and tin can be replaced only by taking the door apart.

Replace gas oven door-mounted gaskets:

  1. Unscrew the door swivel arms and remove the door.
  2. Remove inner console and edge screws as needed. Yous may demand to carefully bend tabs to remove the embrace.
  3. Remove screws holding the window assembly to the panel.
  4. Remove the window assembly to reveal the gasket attachment.
  5. Remove the gasket between the window assembly and the inner door console.
  6. Install the new gasket in opposite order or by following the manufacturer's instructions.
