Our dryer appears to work fine but doesn't dry clothes unless you run them thru 5-6 60 min. cycles. I opened the front access panel on the dryer and saw the heat element come on; the cycle was 45 sec. on and 180 sec. off. This seems like too long an off cycle. I checked thermostat fuses 3-06604 & 3-07473 and both had continuity (closed ckt.). I did notice that the single terminal located on the outside of the heater coil shroud that connects black wire #33 to the front of the heater coil element would spark internally for 1-3 sec. prior to the heater coil coming on. This terminal had no part #. Could this be the problem? Thanks

ANSWER Hello Roger. Yes, a loose connection could be the issue, but the first thing to look for is a restricted vent. 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.
