The cooler at the store has two separate 3 hp compressors. One compressor is able to carry the load, the second one is just for back up. One of the units has been broken for a few years now and I have actually been taking parts off it to keep the other one running. Now the store has decided to fix the second unit.
The broken compressor has a burned out motor. In past years our electrical supply in Brevig was marginal. When the 3 hp compressor would start the voltage would drop very low. This of coarse results in a very high current and extra stress on the motor. Thankfully our local electrical co-op has upgraded their distribution system and we no longer have the low voltage issues.
I am going to change the compressor, install new filter/dryers, install new condenser fan motors, and recharge the system. Most of the work is pretty straight forward, some basic electrical connections, soldering copper tubing, and bolting everything together.
