I have a Sears Kenmore electric dryer. The dryer will spin but not heat. I have removed heat element, a 250 degree thermostat attached to heater element cover, and removed the thermostat cut off (hi-limit thermostat). All of them read continuity. Can a thermostat read good but still be bad? The 250 degree thermostat regulates the heat element? The hi-limit shuts it off if over 250 degrees? I lose one side of 220VAC fuses. Sometimes right side, sometimes both sides.

Check the wall outlet for 230 volts across the outer two pins.

Run the dryer with the back off and check for 230 volts across the thermal fuse, overload thermostat and cycling thermostat.

The thermal fuse has a ceramic base and high up on the heater housing, cycling thermostat on the blower housing.

Sorry. I said that wrong in last reply. I meant zero not infinity. Today I found the thermal fuse and it reads 0. I found the Internal Bias Thermostat, it has 4 posts, the larger 2 (top and bottom) and smaller 2 (left and right sides). I read zero from top to bottom posts. I read nothing on smaller posts to each other, or in any combination with larger posts and either smaller posts. Is that a correct reading? Am I supposed to be able to read small post to small post?
