Hi everyones...thanks to read. I have a Magic Chef model# YE20JN1C (revision "A") on wich the hi-limit thermostat cyles on-off every 30~40 seconds. The control thermostat at the bottom (near the blower) doesn't click off (it's contacts are always closed). My ears noticed that malfunction a few days ago, i thought it was the control thermostat doing it's job, but 2 days after i clearly noticed that the clicking sound was not from the bottom but near the heating element. I hooked a two conductors cable with crocodile cable clamps on each end to this hi-limit thermostat's terminals and the other end to my multimeter. I closed back the top cover and did a drying cycle. Effectively the multimeter showed that it's defetitely not the control thermostat but the hi-limit one that is cycling!

Yes, the outside vent and the ducting is clean! So is the blower assembly the the exaust. :rolleyes:
Please look at this picture i've taken:

There's some openings (not very visible on this pic) at different places between the plastic air guide and the door frame that could produce some air leaks (reduction in vaccum). I would like to start the troubleshooting from there. Any suggestions on what i can use to seal this guide properly? I thought about strands of crack seal or the like... TIA

As a late reply for those who may read my 1st post... i replaced the seal around the blower intake, and also around the collector duct on the front panel. For this one i used weather stripping...the one that looks like play putty. This have a very good adherence to metal and plastic parts as long as is clean from dirt and dust, of course. Now the hi-limit thermostat doesn't cycles, only the control thermostat like it should...and the dryer takes 25% less time to dry items!
