I foolishly went to have a look at a searle cellar cooler today, with flu. I feel quite bad-sitting up in bed now.
Problem is this. Unit tries to start, and cuts out. The guy said that the evaporator had iced up a couple of times over the last day or so, so I thought it must be low on gas, connected the gages and got 100 psi standing pressure. I noticed that the compressor runs on R404A, but the evaporator plate shows the mediums as R12, R22, or R502.So to start with I think someone changed the condenser rig wrong.
As soon as the compressor tries to start, the contactors in the control board click back out, and the compressor stops almost instantly along with the condenser fans. I disconnected the lives from the compressor electric box. The main circuit breaker will stay on, but the contactors will not pull in-as theres no load.
I tested the compressor and found the motor was good, so I think the problem is the start capacitor, but by then I was getting quite ill, and quckly discharged the start capacitor, and but a resistance meter on. The display graph rises to 14.6-on the 80kohms range I think and stays there, instead of going to infinity, but I had to get home quick and go to bed, so I hadn't stayed there that long, but the fact that the brewaker trips stright away makes me think it's the capacitor.
Just a little story I wanted to share with you. There must be a moral to it, because if I had been well, I'd have sorted out. It's amazing how illness affects you, and how foolish it was to mess with the rig while unwell.
Anyway. If anyone has any second opinions, then please reply.
