The heat comes on but never gets very hot. When I put it on more dry, it actually got cooler. What could be the cause?
You will want to check the heater coils on your unit. There are 2 sets of coils, an inner and outer set, and if one of them is burnt out it will cause the issue you are having. If you do a resistance check on the coils there should be 21.8 ohms for either set and if not then the coils are bad.
My dryer does not at all when i push the start button. A few hours earlier it was working fine. what might be the problem?
The 2 things that you will want to check for would be a bad thermal fuse and a bad door switch. You will want to check the continuity of the thermal fuse to make sure that it is not blown. The most common reason for a blown thermal fuse would be a clogged or restricted dryer venting. You will also want to check the door switch to make sure it has continuity when the door is closed. If no continuity then the switch is bad and would need to be replaced.
