Burner maintenance is of highest importance to keep your dryer running efficiently. First, make sure ALL power is turned off and LOCKED OUT! (You’re going into the heat chamber; take no chances!) Make sure the burner covers are removed if cleaning a tower model. Vacuum or blow out the accumulated dust and beeswings (or red-eye). Try not to simply wipe the residue as it will further clog the burner openings, and when you clean out the holes the residue goes into the plumbing train. When the burner is ignited, all that residue re-plugs the holes in the burner.
TWO BURNER TYPES: Maxon & Midco:
MAXON BURNER – To clean the Maxon burner you will need two different size drill bits: One a size # 47 (5/64), and the other a size # 50. They can be easily obtained locally or Grainger has them as item numbers 1V 818 and 1V 825. (They are really small and brittle, take a few of each.) Use them to open the holes in your burner, being careful around the spark plug. A cordless drill works well, but remember the bits will break easily. A cutting torch tip cleaner (drill bit type) also works well.
MIDCO BURNER – If you have the Midco burner its the same procedure, just use a 1/8 inch bit for the gas holes and a # 42 for the air holes (Grainger has them as item numbers 5 TG 11 and 22 N 359).
While you are there it’s a great time to inspect the spark plug and flame sense rod to make sure they are still in good shape. A flashlight is a good item to take with you. Once finished, re-apply power and test fire the burner (jumper the air pressure switch), to make sure everything is ready.
This one simple thing will save many problems in getting your burners lit and it will also make them burn more efficiently.
