Not sure why but my Harman Absolute 63 is giving me fits this year. It is 3 1/2 years old and I burn 4 to 5 ton a year.
About 2 weeks ago I found a distribution wire sitting on top of the combustion/exhaust fan and as that spun it wore through the insulation and shorted it out which in turn took out the control board.
After replacing the control board a few days later I hear a noise that I determined to be the combustion fan. I ran the combustion fan in test mode and it makes the noise then. The distribution blowers did not.
I took the fan out but wasn't able to determine the cause of the noise. I'm suspecting a bearing but there was no slop in the shaft. The fan blades seem fine also.
Any ideas on a possible fix?
If the fan needs to be replaced I read a good deal about sticking with OEM but if the original fan only lasted 3 1/2 seasons how much better are they?
Best place to buy one if need be and OEM or anyone have a good experience with an aftermarket and if so which brand?
Thank you in advance.
