So I have this Samsung dryer, about 4 years old now. Yesterday it stopped producing heat. I'm an auto mechanic so I'm pretty handy with tools and knowledgeable about electricity so I decided to tackle this myself. Upon doing my initial research I found the usual suspects are the heating element, the hi limit switch, or the thermo cutoff located on the heater housing. I ohm'd everything out. I have 9.5ohms across the heating element, and 1ohm on both the hi limit and cutoff switches. Everything appears normal. I checked the heater relay on the control panel. I'm getting 120v on both terminals with the dryer running. No problems here. I checked voltage at the heater element with the dryer running. I measured 120v at both terminals. I'm not understanding how I can have voltage running through the heating coil yet it doesn't heat up. I have checked it to make sure it's not shorted to ground.
Here is the kicker. The dryer has a "smart install" mode that can check the touch sensor operation along with the motor and heater. When I run this mode by holding "adjust time up+the temp key for 7 seconds, the dryer goes into the test mode. The drum spins and it will produce heat for roughy 10 seconds. Then it indicates on the display that the system is ok. So I know the thing is capable of producing heat. It just won't do it in it's regular cycle. I have also checked both thermostats on the blower housing for continuity. Both come out at 1ohm. I'm stumped. The only thing I haven't checked is the centrifugal switch. That would require removing he entire drum for access. Anyone have any advice? I thought this might be something simple.
