RV Repair: a.c relay board, relay board, several different types

Question
how difficult is it to change a relay board. My air stopped working and we bipassed the relays and the fan works so i think the board may need to be replaced.

Answer
Robert, What kind of air conditioner is it? Actually none of them are too hard to replace as long as you get the correct replacement one for the air you have. Coleman's have either 4 or 5 wires to the relay board besides the 110 vac wires. Now Dometic has several different types that range from 4 wire to 7 wires and then they also have like a telephone wires that connect to some. But if you are able to bypass things to do the checking then I feel very confident that you can do this. Thanks, Bill
