I recently fixed a White-Rodgers Model 50A51-242 furnace control module that had a problem with one of the blower control relays. This problem turned out to be so easy to fix that I figured I might as well do a write-up on it.

In my particular case the “HEAT HI” relay was not activating when it should. (For a description of the troubleshooting involved, please see my post on York Deluxe Diamond 80 Furnace repair)

Removing the bottom cover

I used a 1 inch putty knife and screwdriver to remove the bottom cover. Be careful not to push them in too far which could damage the circuit board.

Upon opening I was very happy to see that there were 3 identical blower control relays on the board: one for low heat (“HEAT LO”), one for high heat (“HEAT HI”), and one for a/c (“COOL”). This was good news because it meant I had a spare relay, as we were not using the a/c function. I would be able to use the a/c relay to replace the high heat relay if need be.

Cold solder joint for “HEAT HI” relay

As it turned out, there was no need to replace the high heat relay. A close inspection of the high heat relay’s solder connections showed a very obvious cold solder joint on one of the coil connections. I resoldered this connection, and the problem was fixed. Resoldering the connection did prove to be a little challenging, however. It just would not take the solder. I believe the problem was some kind of coating on the solder. After I carefully scraped the area with a precision screwdriver, and fed in plenty of flux core solder, it finally took the new solder.

I did notice another problem with the board. There are four resistors connected in parallel to provide current to the thermostat. These resistors had obviously become very hot at some point, discoloring the board and melting their solder connections. This probably happened years ago with an older thermostat that drew too much current. Since the furnace is currently hooked up to a digital thermostat, and they draw very little current, I wasn’t too worried. I decided to resolder the resistors just to be on the safe side, but it was probably unnecessary.
