Temp. drop during defrost
Posted: Thu Jan 13, 2011 8:01 am
I have a FRHS0301 unit outside & a AH14X1ona air handler with a 3610-610 heater assembly.
had the defrost board replaced but new one is not demand defrost.When in defrost mode with low
outside temps., the inside temp drops several degrees below set point.This causes the heater to stay on to compensate. This wasn't bad with the demand defrost, but new board is time controlled.
This unit has a 10KW heater with a optional space.Would changing to a 12.5-15.0 KW heater help
prevent this temp. drop? Can this be done without changing the control board?This problem is worst
when the unit cuts off while in defrost mode.
