Will not dry cloths unless I put it thru a couple cycles. I noticed the heat comes on but shuts back of after a few minutes. I by passed the hi-limit just to see and the heat will stay on. This was the lower mounted hi-limit. Is this my problem? I noticed 2 other hi-limits above the one thats closest to the flame.
Thanks for any help.
Answer Hello Kevin. It sounds like the venting system is clogged or kinked. You will need to check the vent and clean it out. Be sure and clean the vent pipe and the dryer air duct assembly. If the air flow is not good, the unit will retain moist air causing the clothes not to dry. Try running the unit with the vent unhooked from the back of the dryer and see if the dryer works properly.
Dryer will not dry load in one cycle. Noticed the gas will turn off and on. I by-passed the hi limit switch and the gas stayed on. Could this be my problem switch. I noticed 2 more mounted above this one (bottom one) Thanks for any info you can send.
Answer Hello Kevin,
I know your reaction to this comment will not be favorable, but it has to be said. The exhaust is the cause of this complaint more than 90% of the time. Think of it like this, the dryer drum is riding on felt seals. If a little too much back pressure is built up, the lint, heat, and moisture will simply blow past the drum seals back into the cabinet. This is actually where the air is taken into the unit and also where the thermostats are located. This causes the thermostats to open prematurely and this will extend the dry cycle.
The exhaust should be a 4 inch diameter rigid, non-flexible aluminum duct that is as short and straight as possible. You see, the shorter and straighter the duct is, the faster and easier it is for the unit to rid itself of the heat, lint, and moisture and the clothes will dry faster, the unit will use less electricity, and the dryer will last you longer since it isn't running a long time putting wear on the mechanical and electrical parts. All manufacturers strongly recommend against the flexible ducting whether it is plastic or the foil type. The flexible ducting crimps off the air flow too much when the unit is pushed back into place. It also holds lint which, when ignited, goes off like flash paper and will cherry inside the duct. The flexible duct will just melt through, (yes, even the foil type will just melt), and then you have the lint "cherryed up" in the floor.
