SOURCE: unit wont start display only shows (hrs)

ok i tapped out and called the repair man. he came and found out the main board is fried.

you have to change the board.

he charged me 350 total for everything.

so all you have to do is order the board and do it yourself.

board is around 200-250 i think

SOURCE: Refrigerator totally inop. 120 VAC & 12 VDC present. Unit is model # RM3662.

Yes, I did the same thing. I had a qualified RV repairman change out the board. He also told me there is a recall on this specific issue and that DOMETIC should pay for not only the board, but quite possibly the cost of the labor to repair.

Dometic phone # is 888-803-0013

What is the operating presesure and temperature for a r-134 commercial refrigerator

Those units are going to give you pressures corresponding to the surrounding area. A hot kitchen will get the head pressure up around 150-170 psi sometimes. The suction is going to be somewhere around 20psi give or take 10 psi either way. You can't trust pressure readings except for an indication that the compressor is pumping and you don't have a deep vacuum from a lost charge or plugged cap tube or blocked metering device. Always weigh the charge into the system. You cant be a hack hvac guy and help a guy by putting gas in his refrigerator. Commercial refrigerators are pretty touchy and don;t like to shut off if they don't have an exact charge. Don't take my word for it call True in St Louis they made the thing. Hope this helps and good luck.

Amount of refrigerant that carries this freezer is 1.6 pounds? "

Those freezers utilize R-404A refrigerant. The amount of refrigerant will be displayed on the data plate on the inside of the unit usually on the left inside panel. It will have the type and weight of refrigerant...

However, yes, 1.6 lbs sounds about right for those models.
