Fan comes on when I nudge the Air Handler

My central air works fine when the air handler blower is working. To get it to work, I have to go into the attic and nudge the air handler. Just a tap and the fan starts working.

Any ideas??

Thanks for any help before the heat comes!!

loose wire or sticky relay..? either way your 'nudges' will probably have to get harder and harder


open up the air handler cabinet next time and take a peek. could be a wire lead just falling off

I have opened the cabinet and checked every connection and they all look good. I'll try replacing the relay?

Thank you

could be the capacitor for the blower motor or the wires going to it.

How about something as simple as the safety switch in the air handler?
