I connected my gauge set to the unit. Pressure on the high side was very low. It is the sign of an inefficient compressor for me. The compressor has a hard time to maintain the temperature, run all the time and that’s why the client had the service light on the screen. Also, I found the clogged drain. As result to that, all the defrosted frost from the coil was coming into the freezer and made huge ice buildup.
I offered to replace the compressor, dryer filter, recharge freon, remove frost and clean the drain.
Here are the steps which I followed during the repair.
First I removed all shelves, cover, icemaker and the back wall. This allows me to have access to remove huge frost build up. Using the steamer I melt down frost and cleaned the drain tube. This is the tough challenge because there are lots of wiring in this solid chunk of ice. I always turn off the power to the unit not to cause short during melting down the ice buildup. After that, I install all components back to the unit.
Second I removed the bottom grill and cover. I cut the old compressor and clean the area around. I installed new compressor and weld all copper pipe connections to it.
Third I cut an old dryer filter and welded the new one. Also, I cleaned the condenser coil as part of the unit maintenance.
Fourth I recharge the system with the proper amount of the freon, which is specified on the label.
Another happy customer!
