My whirlpool refrigerator (model GB2FHDXWB02 ) keeps having to be defrosted. We wake up one morning and the fridge is about 60 degrees and the freezer is still cold. I've defrosted it multiple times. There is always a puddle on the floor after the defrost so something was clogged somewhere. This has now become a monthly occurrence.
Any ideas on how I can troubleshoot this? Can I flush the line with hot water? Replace the fan?
From what I could find based on the serial number that starts "K1..." The appliance was built in 2011 (39th week)
Years ago I replaced the condensation tube with the P-trap replacement part issued from Whirlpool. This issue is fairly recent so it seems they are not connected.
Thanks very much for your help
