Hi, my name is Sean. I have a Coleman 3400-815 that just had a limit switch literally burn out. The wire going to it was fried and so was the switch. I have replaced that switch and now unit appears to be somewhat working. The problem is that only one heating element that i can see comes on for a few seconds and then shuts off during heating. Then after another few seconds it repeats. The air from the vents are only about room temperature. Do you think the rest of the limit switches could be bad or could there be something else, possibly something that may have caused limit switch to burn up so bad. My other concern is that the blower stays on all the time now as well. Thanks in advance for any insight you may have on this issue.

Hi,

May have a bad sequencer . It controls the elements and blower.




Thanks,
Robert
