Inside blower turns off - outside AC keeps running

Hi! New to the forum, but this seemed to be the best place I could find to post my question, so here goes!

I've a Coleman Presidential Model 7900C Series Furnace (Standing Pilot)

The blower on the furnace will shut off...but the outside AC unit keeps running, and can only be shut off via the circuit breaker...just moved in..so not sure what caused this...wiring from the outside AC unit to the Furnace seems to be.."questionable" in the way it's hooked up..thermostat seems to be working fine.

Any guidance would really be appreciated!

Hi,

Contactor in outside condensing unit stuck closed, short in wiring somewhere or faulty thermostat.



Thanks,
Robert
