Gas ranges can more comparatively more dangerous than electrical ovens when in disrepair, so having a checklist of common parts to check for damage when you’re servicing an appliance is a great way to help your customers. Orifice holders can get damaged or are sometimes missing entirely, and it’s a part you can check over with just a quick glance. If an LG gas range you’re working on needs a left rear orifice holder, order part #MBE61841301 and make the repair by:

  1. Unplug the oven before making any repairs, and shut off the gas supply.
  2. Remove the grates, burner caps, and burner bases so you have access to the top panel.
  3. Unscrew the fifteen screws holding the top panel to the orifice holders and release the clips so you can remove the top panel entirely.
  4. Release the spark electrode bracket. You will need to straighten the retaining clip holding it in place and then set it to the side so you can access the holder.
  5. Remove the orifice.
  6. Loosen the nut holding the burner tube to the holder.
  7. Unscrew the holder and install the new part.
  8. Secure it with the mounting screw, and then replace the parts you have removed, starting with the burning tube. When you’re putting the orifice back into place, be sure to add a bit of sealing putty on the threads for an airtight, secure fit. Next, replace the spark electrode and snap the clip back into place.
  9. Replace the top, but make sure the electrodes and holders are in place through the slots before snapping the top panel fully into position. 
  10. Reposition the screws, burner bases, caps, and grates.

Knowing how to troubleshoot and repair both electrical ovens and gas ranges will expand your client base without making you drive further and further. Go to Appliance Express for more repair procedures and troubleshooting tips.
