The compressor should have 3 electrical terminals attached to the housing from inside the compressor. S – R = 11 Ohms. Find the terminals marked C, R, and S. Your compressor should have three terminals on it or in the access panel. For instance if C to S reads .02 ohms and C to Run = .04 ohms, then C to R should be around .06 ohms. is it common, start ... . They will be marked as R, which is the run line; S, which is the start line; and C, which is the common line. If you measure between the run winding and the start winding, you should get the sum of the other two readings. It is a red wire and comes from the transformer usually located in the air handler for split systems, but you may find the transformer in the condensing unit. I wonder if I could use the H terminal to run a wire to W on the furnace. Answer Save. You should be getting 24 to 28 volts AC between the R and C (com) terminals on the control board and when the thermostat is calling for cooling you should have 24 to 28 volts between Y and C, G and C, and of course R and C. If you are not getting 24 volts to R and C then you probably have a transformer problem or a blown fuse on the transformer. A single-phase compressor has three slide-on terminals. Wiring is: (T-Stat - Furnace) C - B/C. Run, Start and Common. * C.S.R adalah singkatan dari: C : Common S : Start R : Run. 0 3. We read 43 amps on our amperage meter and 230 V at the compressor terminals. S goes to the HERM terminal on a capacitor with the other side of that capacitor (C) going to the same leg that feeds R. C what I’m saying? Power from fan relay to fan motor will typically connect to the T2 terminal on the Contactor relay. Confusing. on a compressor, what do the leads R, S, C mean? 2 0. Lastly, if you have a package unit, then the transformer is in the package unit.
