57T01-843 – FAN CONTROL BOARD (TIME DELAY RELAY, TRANE, RLY02807)

If your Trane air handler blower shuts off immediately when the compressor stops — instead of running for another minute or so to push remaining cool air through the house — this time delay relay is the fix. It keeps the blower running for 80 seconds after compressor shutdown.

Specs: Time delay relay, 80-second fan-off delay, OEM Trane

Replaces: 57T01-843, CNT05981, CNT5981, RLY02807, RLY2807

Fits: Trane and American Standard air handlers.
