I have a Mt. Vernon AE insert that looks to me to be 06/07 vintage. The control board has a mfg. date of 03/07. At the end of last season it started to skip its autoclean cycle. Everything else would work fine but eventually it would fail to ignite because of the firepot being clogged with ash. Today I gave the stove a preseasen cleaning and tried to remedy the autoclean issue. I tried crimping the female connectors closed on the 10 pin harness and the autoclean motor harness. I thought that fixed the problem, during testing when I powered up the stove it would go through its normal startup functions. Now when I power it up it will not run its autoclean cycle. I will hear the autoclean motor make a brief 1 second click and the stove goes to ready or off depending on which function I have selected. When it was testing ok I would get an autoclean reading on the thermostat control, now I get no autoclean reading , I get the quick motor click and it goes to ready. Could this be a control board issue or do I need to be looking elsewhere?
