woke up the other morning finding the stove burning down with no power! i say to myself, what the heck is going on here? no lights lit up, mmm. unplug & replug stove and same result. check fuse and it's burnt out. replaced fuse and all is well. going out of town for the weekend so i turn stove off and i let it cool down. i get back from my trip out of town to find the stove down again with no lights, mmm. burnt fuse again so i get dirty and dive into the stove for diagnostic search. i found the combustion blower is making a squealing sound so i sprayed some penetrating oil around the seal behind the exhaust fan to see if it helps any. no, squeal is still there? i spray at the motor to shaft area and the squeal went away this time, mmm out loud! at the same time i was doing a wattage check and it was about 80 watts on combustion fan only before oiling and around 68 watts after. combustion fan and distribution fan together i get 100 watts and when the feeder kicks in i get 130 watts. it has been a hour since the stove has been running and the wattage has changed to 116 watts and 146 watts, an increased of 16 watts for now. i gather the combustion fan is on it way out. anything else i need to check or do or do i just order another combustion fan(hopefully it's the culprit)?
 
You probably hit the fan on head. Kill a watt online for checking things? I run one most of the time. Great to get a baseline measure of systems. Well worth the less than $20.
 
Nice diagnostic work. I'd say you got it nailed.
 
thx,
a blown fuse is usually associated with increased power demand so i did use my kill-a-watt meter to observe what's going on. first fuse burnt since ownership of stove(5 yrs), it has treated me well. stove is still operating as we speak so thumbs up for now. i'm glad this happened when the cold snap was over, thank god! now to the search for a new combustion fan...........
