OT! Air Handler

in THE MAIN WALL
Hi Wallies,



What would cause a condenser contactor to click on for ten seconds, off for ten seconds, repeatedly on a call for AC? A friend of mine just called me with this. I figured I'd check the stat wiring first then the blower motor board. Anything I might be missing?



Thanks in advance, Adam

    low pressure

    Sounds like it's cycling off on low pressure. When the contactor drops out the pressure comes back up enough to make the psi switch. Then it pulls back in and pumps back down until the switch opens up again.
