C = Common S = Start R = Run. all electricity for it to work needs a path a load and a source. Inside an air conditioner compressor is a motor with two windings: a high-current coil called Start, and a low-current coil called Run. A technician needs to check the winding of a single phase compressor; he labels the three terminals "A," "B" and "C." He took the following resistance readings: "A" to "B" 10 ohms; "B" to "C" 20 ohms; "C" to "A" 10 ohms. I assumed the P must be a rubbed off R and V may be a rubbed off Y. Record resistance values for the following C-S, C-R, S-R. On an operational compressor you may see readings as follows C-S 3Ω, C-R 1Ω, S-R 4Ω.. Common- Start will always have a higher resistance value than Common - Run as the start windings are heavier to deal with the in rush current required to start the compressor. S – R = 11 Ohms. Beri huruf [ tanda pada terminal ] misalnya A.B.C. G or G1. Feeling Alive All Over Again!!!! im not so sure though. Yes, L1 of the single phase supply is terminated under terminal L1 of the three phase contactor. Recreational Supply Corporation? Find the terminals marked C, R, and S. Your compressor should have three terminals on it or in the access panel. 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. is it common, start ... . Wired. Compressor Family Series Either a number or a letter established for each product model. Answer Save. * C.S.R adalah singkatan dari: C : Common S : Start R : Run. so u need to know what terminal is for the start and the run winding and the common comes in to play because the csr terminals make a path for electricity. G or G1 controls your HVAC fan. Example – C -S = 7 Ohms. Ukur tahanan masing-masing terminal dengan avometer pada sisi range ohm. There are three different terminals in most a/c compressors. Lastly, if you have a package unit, then the transformer is in the package unit. If you have resistance between Start+Run and have OL at the others, then you the compressor could be off on overload (check if compressor is hot with back of hand or better yet an infrared thermometer). That is, provided it’s connected to the C terminal on your furnace/air handler control board. The suction pressure at the compressor is 43 psig and the condensing pressure at the compressor is 260 psig. Compressor contactor relay T2 to R on the Compressor motor terminal. Wiring is: (T-Stat - Furnace) C - B/C. R goes to the other. Commonly, they are labeled C, R and S. Test the continuity between all three possible two-terminal combinations: C and R, R and S, and S and C. Wait for the compressor unit to cool down after operation before beginning the continuity test. Lv 7. Relevance. 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. While the thermostat supports 2-stage operation, it currently is configured for one-stage, as that's all the old furnace was. We read 43 amps on our amperage meter and 230 V at the compressor terminals.

Mine also has one marked H. Must be Humidifier. If you have a two-stage compressor, Y2 controls your compressor’s second stage, allowing for different levels of heating and cooling. This is different from a single phase compressor which will have 3 terminals listed as S, R, and C (Start, Run and Common). Pump Down First, many scroll compressors won’t even allow you to pump them down into a vacuum. I wonder if I could use the H terminal to run a wire to W on the furnace. So compressor terminals. They will be marked as R, which is the run line; S, which is the start line; and C, which is the common line. on an air conditioner compressor, what are the C.S.R terminals? 2 Answers. With 208v or 240v circuits the L1 and L2 high voltage incoming lines make no difference which is which when you connect. Still have questions? Run, Start and Common.
