I replaced it with the exact model and everything works smoothly. Anybody knows what is Capacitor I should buy? You need to use a relay circuit when wiring in the hard start? Shipping cost, delivery date, and order total (including tax) shown at checkout. If there is enough space for mounting, using two separate run capacitors in place of your original dual run capacitor is acceptable. Run capacitors create a charge, or current to voltage lag, in the detached start windings of a motor or engine. Anyhow he charged us $330 to replace the run start cap and because Im pretty sure he didnt have the right one on the truck, sold me a song and dance about how a 55/5 cap would give our dying compressor the jolt it needed to start over the 45/5 that was in it. Maybe the fan motor he replaced it with required a higher one? He said this would work as good as the original. Get Quote. I thought the dual capacitor took care of starting and running the fan? The capacitor has an obvious bulge on the terminal end, and after removing it and testing, dual cap, Several factors may be interchanged or combined to increase or reduce the life of a run capacitor, but once the design life is exceeded, the internals may begin to more rapidly decay and drop in performance. Ive found one with the exact same specs (30/7.5 MFD, 440V, size) on Amazon. I see a red wire coming off the contactor to one side of the capacitor and the other side runs back to the compressor (which I assume is the start side of the compressor). He replaces the old capacitor with a brad new AMRAD Turbo 200.Read all . A higher number on voltage 440 versus 370 is okay. Capacitors are not very expensive like the other components of an air conditioner. If the fan started after that the capacitor is most likely bad. Possible Replacement: P291-3074R. They are only intermittent duty and will fail catastrophically if energized too long. Im only 2 months into the training, so I hope I have this concept clearly understood. Data Sheet. Capacitor MFD rating. Our AC stopped working yesterday and after a few calls we got someone to after 5. Could it be the fan motor was working working off two capacitors and I accidentally disconnected one? Description: 30 MFD.
