There is not heat at all, only cold blow but i changed once the heater element less then a year ago then it was working but now again there is no heat at all and i took out the heater and see it no damage or cut wire like one i get it replaced before. I am stuck now what and where to check next as there is no heat, only cold blow. If you can tell me what part it cost this problem and i'll bye it. Please respond me back asap i am in hurry to get this fix, thanks you so much!!

Yes its helpful as you said that, and i have done bypass it the thermal cut-off and the high-limit thermostat 250 F then i start to turn on let it run about less than a minute and i see it heat up. At this time i'm still waiting for both parts ordered online to come and receive. When i receive the parts and will put on then i'll let you know the result, but i am sure 100% that will fix it and its the problem with thermal cut-off (it cut-out) and high-limit thermostat as you said, right. May i appreciate and thanks you very much, Jahn27 and this Service as well.
