Most likely a bad fan motor or capacitor if it will not run in ON or auto position.Do you have a volt meter for troubleshooting?
After burners come on within 30 seconds we should get 120v at COM and HEAT terminals on board

HEAT terminal should be right below COOL

Where do fan wires come from? Can not see the here
Where do they go on board?
Are they plugging onto the board?
OK but you get no voltage between white and red on call for heat?
If this has worke wired this way in past (although shows different than my 376 manual I suspect relays on board are bad and you will need a board
That is not the board I show, but Bryant (Who makes day and night)could have changed board in the series at some point. Here is the manual I have. See board on page 8
I am about to leave for the evening.Do you want to continue tomorrow?
Yes. Now doing some research I do also show a CESO110057-02 that says it fits your furnace.
This is most likely your problem though is that although you hear the relays click, they are not closing.
I am showing 3 different boards so they must have changed along the way.
Not sure what time I will get in office tomorrow.Would you like me to open question so other experts may assist if I am not here?
OK I believe if you get that board it will fix you up.I will check on you tomorrow.
If you are simply told to replace the board based on all the troubleshooting we have already done. please rate my answer so I am accomodated for the time troubleshooting.I am only opting out in case I m not here when you return.Thanks again.
I am in office now.
