Question about Ruud UAMB Air Conditioner
I have a UAMB-042 JAZ unit. Sometimes the A/C will kick on and within several seconds the outside unit will stop and the inside unit will keep running. If you go outside and push the high pressure reset button the unit will start and continue to run. I have had it cleaned and checked for freon. They also changed the fan motor and drained the freon to see if the expansion oriface may be clogged. The unit still has the same problem. The problem is intermitent and hasn't occurred with gauges attached to troubleshoot. Any ideas or help are appreciated.
Hi, If the outside fan is running when this takes place and the condenser is clean, I believe its the High Pressure Control that is bad. There is a possibility that if the unit was opened and air was allowed to get into the refrigerant part on the system that it could cause this problem but unless the system was worked on just prior to this starting, I don't think this would be the case. The part about draining the freon to check the orifice doesn't sound right, This could be done with a pump down by closing the suction line valve at the condensing unit which leaves the freon in the condensing unit. If they charged you to replace the freon, I would question them about this procedure. Hope I have helped. kstfas
