Came home to a COLD house yesterday evening, and the display on the furnace was flashing '6' then '8'... I understand if I turn it off then on, it reads the last 5 error codes starting with the oldest first? But just in case, it flashes '2' and '2' as well when starting up, then '6' and '8'. It sounds like the blower tries to start up, but cuts out right aways. The burners light.
Would this be the blower motor needing replacing or a control unit? The guy who looked at it, and installed it, wants to replace the blower motor first... just thought I'd check here, he said he was unable to test it.
