so im doing maint on an older R-12 Victory reach in stainless 3 door cooler ( still running on R12 ) , turned off condenser to clean coil and oil fan motor , after done turn on condenser assembly , immediately fan begins to rotate and i hear a click from compressor ( tecumseh ), fan continues to get to full speed in about 5 seconds ..... then 10 seconds later it fires up with ease.
Let it run a few minutes and during that time im wondering what that click was .... turn it off again. Wait 5 minutes. Turn back on , same thing , click , 10 seconds later fires up.
The owner is a retired tech and just dont like messing with refrig anymore. He's got R12 in the little 12 ounce cans.
Only thing i noticed that was strange was top half of compressor sweats and is cold.
But keeping a 36 degree box , i didnt mess with anything.
Being more experienced in residential , I wasnt sure if this old cooler had some sorta delay I wasnt aware of. I will replace start components this morning.
You should see frost on the suction line entering the compressor but the top half shouldnt be cold and sweating. Sounds like it may be overcharged. Pressures are high.
The click sounds like OL. Bad start and/or run capacitor or weak OL.
Id recover and get the charge right to begin with.
