The board in my 880 maxx is fried. I purchased a new board off ebay that is number 6600-56 Rev C. My old board is 6600-155 Rev 9.61A . What I read is that the EPROM has to be moved from the old board to the new one in order for it to function. Is this correct? Is the EPROM only the one long rectangular chip?
Freezing temps moving in and I have no heater.... Please hurry
Thank you for any assistance! Thanks.

I replaced the board uusing the eprom and same jumper settings. Still no heat. I have 240 v to the heater relays but nothing coming out for power. Ohm test on heater is 9-12. what controls the heater relays?
Update. I installed a new flow sensor and transformer but still can't get power through the K1 relay. I have 240v to the relays but nothing coming out of them. Any ideas? No error codes but NO HEAT
