How do you remove magnetism from an electromagnet?
Apply AC Current One way to make a magnet is by applying an electrical field (electromagnet), so it makes sense you can use alternating current to remove magnetism, too. To do this, you pass AC current through a solenoid. Start with a higher current and slowly reduce it until it’s zero.
How to clean AC coils with household detergent?
How to Clean AC Coils with Household Detergent While there are a number of commercially available coil cleaning solutions on the market, air conditioner coils can be cleaned with a solution of a mild household detergent and water. The detergent and water mix is applied to the coil using a low-pressure sprayer.
How do you test an AC clutch coil?
Touch the other wire to the positive side. If the magnet is good, the compressor clutch will click into place when the magnet powers up. Release the clutch by removing the positive wire. Repeat this procedure several times, each time listening for the clutch to energize. If the magnet is defective, replace the compressor.
What to do if your clutch coil shorts out?
If the clutch coil shorts out, the positive wire may begin to heat when it touches the positive battery post. If this happens, quickly remove the wire and replace the compressor. This could also happen if the two, small connectors are touching each other.
What to do if your magnetic contactor is not working?
If the answer is no, you may have an open circuit keeping the power from reaching and activating the coil. To be really certain, check the voltage at the coil terminals while it should be turned on. If the voltage is present, turn off the power by unplugging from the wall outlet or by shutting the circuit breaker down.
Apply AC Current One way to make a magnet is by applying an electrical field (electromagnet), so it makes sense you can use alternating current to remove magnetism, too. To do this, you pass AC current through a solenoid. Start with a higher current and slowly reduce it until it’s zero.
Where is the field coil on an A / C compressor?
Align the dowel pin on the back of the compressor clutch field coil (2) with the hole in the front of the A/C compressor (3) and position the field coil onto the compressor. Be certain that the compressor clutch field coil wire lead is properly routed so that it is not pinched between the A/C compressor and the field coil.
How do you remove an AC accessory belt?
Remove the air conditioning accessory belt with the proper size wrench in your wrench set. Disconnect the connector on your compressor’s magnetic coil. Use the right size socket to remove the 6 mm bolt in the center of the AC clutch.
