The first time I turned it on this year, Jan. 2010, it came on, made the normal stage noises, and started to blow nothing but cold air.According to the guide, it tells me to clean the flame sensor. I cleaned it after talking to several HVAC people I deal with. I am in the electrical trade, and am no idiot.I am very mechanical, & technical with my job,and have to know & posess knowledge of all facets of my industry, & understand systems and devices. The cleaning did not produce any change. I measured the resistance across the sensor & got a reading, telling me it was not open, & had resistance. My next step was to order a new OE part from Modine, thru a local supply house. I replaced the sensor, and I am still having the same issue, it comes on for about 2 to 3 minutes, then the flame goes out. The roll out limit switches are not tripped, and all seems to be funcitoning properly, ..except for the flame keeps shutting off, & the unit goes into the restart mode. I am more than a little pissed off. What should I be looking for, what should I check ? My Hot Dawg has been in service for 4 years working perfectly.
