How do I check the continuity on my refrigerator compressor?
How do I check the continuity on my refrigerator compressor?
Check the Thermostatic Control Set the switch between 4 and 5, and check for continuity between the plug and the wires attached to the start relay. The meter should display a ‘0.000’ reading between each side of the plug and one of the wires attached to the start relay. If either side gives you an ‘O.
How do you test a deep freezer compressor?
How to Test a Chest Freezer Compressor
- Step 1 – Take Readings. Read the instruction manual of your chest freezer as not all appliances are the same.
- Step 2 – Turn on Your Freezer.
- Step 3 – Check the Evaporator Coil.
- Step 4 – Identify the Noise Generated Inside Your Chest Freezer.
Why does my fridge compressor kick on and off?
An incorrectly adjusted thermostat can cause the freezer’s compressor to start and kick off. The compressor provides the power behind the cooling function of the freezer. Set the thermostat to a lower setting to see if the compressor starts and then stays on. If it does, the compressor doesn’t have a problem.
How do I check for bad appliances?
Measuring Resistance in Seven Easy Steps
- Turn off and unplug your appliance.
- Remove the potentially faulty part from your appliance.
- Turn on your multimeter and set to the lowest resistance setting.
- Test your multimeter is working by pressing the probes together.
How do you troubleshoot a freezer compressor?
- Check the temperature setting.
- Clean the condensor coils.
- Unplug the freezer, wait two hours and plug it in. If you hear it running, a problem is causing the compressor to overheat.
- Test the temperature control.
- Test the evaporator fan.
- Test the defrost timer.
- Test the compressor relay.
- Test the overload protector.
How do I know if my compressor relay is bad?
The Shake and Rattle Test Unplug the start relay from the compressor and give it a shake. If you can hear rattling on the inside of the start relay, then the part is bad and will have to be replaced. If it’s not rattling and appears to be in good condition, you may have a problem with the actual compressor.
How to test the start relay of the refrigerator compressor?
Step 1: With the relay in the vertical position, coil downwards, check if there is continuity between terminals 10 and 11 of the relay. If there is not, change the relay. Step 2: With the relay in the vertical position, coil upwards, check if there is continuity between terminals 10 and 11 of the relay.
How to test a single phase fridge compressor?
How to test single phase fridge compressors electrically. This test shows if the windings on the motor are ok. If the compressor passes this test but it can’t start probably the starting relay (PTC relay) is broken or the problem is not electrical but mechanical. So the next step I’d recommend is to focus on the starting circuitry.
How do you check for continuity in a relay?
Step 1: With the relay in any position, check if there is continuity between terminals 1 and 2 of the relay. If there is not, change the relay. Step 2: With the relay in the vertical position, coil of the relay upwards, check if there is continuity between terminals 1 and 3 of the relay. If there is not, change the relay and repeat step 1.
What’s the best way to test a gas compressor?
Now test the compressor for ground. With the multitester still set to X1, touch one probe to bare metal on the compressor housing (it may be necessary to scratch away a little paint to expose the metal). Touch the other probe to each of the three terminals in turn.
