Pete, cold
beer tomorrow? Probably not.
Reported Facts.
2. on startup ammeter showed 6.8 amps then gradually went down to 3.6 amps and stays steady at 3.6
3. AB "power plate" holding plate cooling down a bit but not what I would call cold after about 2 hours. cold line is condensating. Still staying on without stopping or any error codes.
4. I can hear a very slight hissing sound coming from the cold plate.
Pete, Letting out some refrigerant is not going to provide very cold beer tomorrow based on the facts you were given on this forum.
2.Compressor starting amps are almost always higher than then they eventually stabilize at after a 10 minute
pump down.
3. This is not a standard evaporator or a holdover plate it is an Adler Barbour
power plate after
compressor run two hours. Temperature off plate line had cold
condensation only.
4. A very slight hissing sound coming from
power plate.
(Or perhaps Richard, you can please advise us how the suction line can show signs of evaporation occurring, other than being over charged with refrigerant? ) Pete Glad to help, I will again try to De Bunk your suggestion to remove some refrigerant.
The amperage of 3.6 amps is not enough to support a too much refrigerant theory. Would not the amperage be higher if there was too much refrigerant in system? And if too much refrigerant was the problem why wasn’t there a LED code signal?
The slight hissing sound can be interpreted as not enough refrigerant or with Superman’s eyes you might be able to determine there is too much refrigerant. Yes, there are techs who claim they can tell when refrigerant charge is correct but I also question that theory.
I believe there are two probable causes of this systems poor performance:
Low on refrigerant.
Moisture in refrigerant? The hissing sound in power plate if steady for more than 20 minutes without interruption and no pauses long enough to allow ice to melt and reform in capillary tube. The melting and freezing will act as a 33 degree thermostat producing only cold
condensation on plate and line but no frost.
