Probable Solution
Clean filters
Clean condenser
Reduce room air temperature
Check purge valve, check
curtain
Check inlet valve
Add refrigerant, if cycle time
drops, check for leak
Check evaporator superheat, if
significantly low or high,
replace TXV
Check pressures fans cycle at.
Replace fan pressure switch if
too low
De-scale water system
Check harvest assist solenoid
Check and adjust bridge
thickness
Increase room temperature
Clear ice away
Check curtain for proper swing
