I was working on a walkin cooler to night. weather got bad so I had to leave and go back tomarrow. the comprsor was going off on over load (high limit)
was pulling 23 amps rated for 12 or 13. 300 high line temp was 97. 25 low (i think temp was 57. not sure what freon in it.with a marker all i could read was r40? the tag on the unit was r12. the compresor is only 3 mounts old so i dont think its r12. the cooler temp 46 about 85-90 out side.
when the compresor was put in thay left the old liq dryer in.
Can someone tell what freon is in there by the presure iam running? or am i running high head?
is the high run amps do to freon?
if the potential relay is bad could this make high amps?
any in put would be great. I dont work on alot of cooler so just wonted some in put.
I only had 15 minutes on the job before the weather and it got dark so i will be headed there again to see what is going on.
thanks for all the help.
