aux fan October 17, 2006, 11:53:10 AM after tracing around the wiring finally got the main fan to operate as it should but since my A/C is inoperative the aux fan will not come on because it has no head pressure to measure and temp doesnt reach above the main fan temps it really does no good. was wondering if it would be possible to just tap the wiring from the main fan and just run them both in parallel (both kick on when temp reachs the 195-200 mark) would the realy be able to handle both? I know there are posts about using a switch but dont want to do that. thought if both would run at once wouldnt have to worry bout turning anything off and on. Quote Selected
