Miller m1mc 090a furance problems
Posted: Sat Feb 18, 2012 2:04 pm
I apologize for the trouble and for this being my first post instead of something contributing or an introduction
However I am having problems with my furnace and have lost heat and hot water 3 days ago.
Model Number: Miller m1mc 090a BW
The problem is that the ignitor heats up and calls to turn the gas on. Sometimes the gas valve closes immediately (we think the control board is telling it to turn off). A flame appears and is sensed by the control board for literally 1 second. Then it shuts off. The led light flashes red 4 times. Thinking that it could be a problem with the control board we ordered one and replaced it today. However the same symptoms are occurring. The led light still flashes red 4 times. Also the blower does turn on but turns off while the yellow light blinks indicating a weak flame.
We also checked to see if anything was clogged or stuck and see nothing that could cause problems.
Any suggestions or should we call rotorooter for a heat system inspection?
