Erstere sind deutlich kostspieliger, verfügen aber über ein integriertes Kühlaggregat. 2 DS18 PRO-DR250TI 2" VC Titanium Compression Driver 8-Ohm Car Horn Tweeter Pair. You can buy a multimeter from a hardware store or online. A freezer’s capacitor plays a role in controlling air temperature and keeping food cold. Many appliances, such as air conditioners, also have a run capacitor that works in conjunction with the compressor contactor to send steady jolts of electricity to keep the compressor and fans running. When testing across the compressor terminals, first make sure all the terminals are bare, nothing connected to them and the terminals are not corroded. If I can’t start it that way, it’s most likely a mechanical problem, most often binding bearings, and the ‘bottom line’s the same: either the compressor or refrigerator will have to be replaced (I’ll be discussing test cord procedures, and how to make your own, in a future article). Connect one meter lead to a good ground (the battery’s negative terminal works the best). Eismaschine mit Kompressor. Lets say 5 Ohms. This tip will be like an episode of Columbo, we will start with the what and who and then get to the why. Ohm Check Compressor Clutch Coil ⇐ Previous Article. With vehicle off turn the compressor shaft with a 14mm socket to check for smooth rotation. The current drawn is about 17.6 amps, tag says max current is 6.5 amps.
