OK wide open, DO NOT REPLACE THE TIMER!!!!!!!!!!!!!!!!!!!. the reason the timer runs all the time is because there is no heat. So the timer is good. If you have a meter, check the element for continuity if you get nothing replace it, if you get any reading it is good. Above the heating element on the top of the heater housing is a thermal fuse. Pull the wires off of it. If youi get any reading it is good, if no reading replace it. OK, I assumed you had a meter, when you said 240 volts was there. Unless you used your finger, let me tell you how to check it without a meter. The thermal fuse that I was telling you about, take the two wires off, and jump the wires out. Then plug the unit back in, and see if it heats. If not replace the element, if so replace the thermal fuse. If you need me you can reach me at my web site at ApplianceEducator.com Tom |
