Question about Dryers
The rythmic rubbing sound you are hearing could be coming from a few sources. It could be drum support rollers that require lubrication, bulkhead screws that have come loose, the drum seal not seated properly, or a silencer plate that has come off the compartment side and is rubbing on the drum.
First, look inside the dryer along the seam where the drum meets the front and rear of the dryer. You should not see any part of the felt drum seal protruding inside the drum. Sometimes the seal starts to come loose or becomes misaligned and sticks through inside the drum. This will cause thumping and excessive noise. If you have anything caught in the drum seal (i.e., a screw, change, etc.) this can also cause excessive noise.
Remove the dryer top panel and start the dryer and watch for anything obvious rubbing on the drum. The top comes off by removing the screws in the rear and sliding the panel back, then up. (CAUTION: DO NOT get your hands around the drum while it is rotating and any of the electrical connections). Look for any vibration from from the rear bulkhead (this is the back wall of the dryer where the drum rides against). Sometimes the screws holding the bulkhead to the cabinet come loose.
Another thing to look for is a metal silencer plate that is usually mounted along the side panels. This plate is glued on and is used for noise reduction. Sometimes it comes off and will rub against the drum.
If everything checks out good, remove the lower panel under the door by removing the screws under the bottom edge (HINT: Placing a small block of wood under the front feet of the dryer can make this easier). The panel will drop down then come off. If it gets stuck, tap on either side to knock it loose. Start the dryer again and look/listen for any noises coming from the drum supports. The drum rides on the drum supports and they require periodic cleaning and lubrication.
The drum light could be a lamp socket problem and/or wiring. Make sure you are using the correct bulb as well. I believe the bulb is only supposed to be a 25W bulb. This isn't related to any long dry time problem.
The heat problem could be directly associated to clogged dryer ducting. If the dryer is full of lint when you open it, you will have to thoroughly clean the vent ducting and interior cabinet. NOTE: This is a fire hazard!
Some things to try: Remove the dryer exhaust hose and start the dryer. The air leaving the back of the dryer should be forceful and hot (about 140 degrees F). If the air flow is weak and cool, you have a clog INSIDE your dryer. If the air flow is normal, check the vent ducting from where it leaves your dryer to where it exits your home. The dryer ducting should be cleaned routinely and kept clear of obstructions.
Your heat problem may not be a component at all. Double check your dryer interior and ducting and let me know what you find. I hope this helps you.
