Hello Folks, I have been chasing my tail long enough trying to diagnose this defrost issue without a tech sheet, would one of you be kind enough to post or email me a copy?

I am having to shut down the comp. and run the evap fan with a heat gun till it quits raining down the drain, the running charge is @ +/- 5 psi on the 134a scale after an hour and will run for a week or so till it frosts over, depending on the traffic. Thermometers on either side telling me what is going on

Unless you have a way to test the thermostat, or how to force it into defrost to test the board, have'nt yet checked the heater bar, just trying to keep from losing more groceries and doing a quick defrost for the time being.
Thanks in advance!
John
