Sears freespirit 30516

if your machine has a timer the timer could be bad or it's the motor,these are the last two things that could stop your dryer from having no heat,next time send the model number,also did you check where the plug connects to the dryer to make sure you have 240 volts going into the dryer,that's the first thing to check,but to answer your question you get 120 volts from the timer or board and the other 120 comes from the motor,you need 240 volts down to heater to have heat.

Find out what is overheating it. Most likely something jammed into one of the rollers.

Tighten up the bolts at the bottom, the ones holding the mast.

Its very unlikely that its the console, however if you still would like to buy it you can try sears canada

Sears sell the Free spirit product and should be able to supply parts.

If its a Icon Health and Fitness branded treadmill (proform,image ,healthrider etc.)The safety key activates the on off switch for the console. (micro switch activated by safety key)Check for 9-12v going to console. Unless it has a magnet switch. What brand and model ?

If calibration doesn't work replace controller.

There should be a wire diagram on the motor tag or under the coverplate. Eric

Hey there,

If your treadmill has an optical speed sensor and hasn't been cleaned for a while, dust, dirt or lint may be obstructing the infared eye of the speed sensor. Try cleaning the treadmill.

Or maybe you need to replace the upper display, although, you may have a loose wiring harness that would cause the same problems. Open the motor case and verify the wiring harness is plugged into the lower board snugly. Also, remove the upper console and verify the harness is plugged into the back of the console snugly as well.

Definitely, inspect the components and try and isolate the source of the problem yourself first, before contacting a dealer for parts, as they can cost a fortune..

Good Luck!
