And one fan will come on with the air conditioning, and one fan will come on when it reaches a certain temperature. If that fan is not coming on... The fan, when it reaches a certain temperature, that's the one that won't come on. Right. So we have to find out why. It's either that sensor, it's either the fan motor itself is bad, or, as I said, something's got to the wiring.
