Set your multimeter to Ohms. Start by completely disconnecting the spindle motor from all power sources. Check each wire, including T1, T2, T3 and the ground wire. If the reading is infinite, your motor should be fine. If you get a zero reading or any continuity reading, you have either a motor problem or a cable problem.Testing the Compressor A three phase compressor will have three terminals. T1 – T2 – T3. Remove the wiring from the three terminals before testing. Set your multimeter to read ohms. Check the compressor for resistance to ground. With the wiring removed from the compressor terminals, test the resistance of each terminal to ground.
Method 1. Test a Capacitor using Digital Multimeter – Resistance Mode. To test a capacitor by DMM (Digital Multimeter) in the Resistance “Ω” or Ohm mode, follow the steps given below. Make sure the capacitor is fully discharged.

I have ruled out loose connection etc. and it all points to the compressor. What I have found is that the run capacitor which should be 20 uF is 14 uF and the Start relay contacts have arched and corroded away.I’ll also go over everything that you need to check in your AC condenser—step-by-step. Check the air handler unit. Check for power to the condenser unit. Check the fan capacitor. Shut off power to the condensing unit. Remove the service panel on the condensing unit. Find the fan capacitor. Inspect the fan capacitor.The first step in troubleshooting noisy contactors is therefore to check the power input from the control source. If you think there is insufficient current coming in from the control source, you need to check its ampere rating to see whether it is high enough to pick-up and seal the magnetic coil. 2. Control Voltage.Grounded Winding – This is similar to the shorted winding but the wire with the broken insulation is making electrical contact with the compressor casing or ground. Here is how to check the compressor motor if you suspect it has failed; Disconnect power. Remove the top of the outdoor condensing unit. Unplug the 3-prong plug on the compressor.Follow the troubleshooting steps above to figure out what the compressor problem is and repair it.

Dometic Fridge Not Cooling On Gas Or Electric. When it comes to the gas issue, the most likely suspects are the burner control device, the gas burner, or the gas valve. If they are not malfunctioning, in which case you need to replace those parts, you can clean them up and get the dirt out. This helps the gas move freely and do its job.It isn't useless. It may not be something you use every day, but I have needed to ohm out a motor or compressor a handful of times, and it got me out of a pinch. So, here it goes: The lowest ohm reading is between Common and Run; The middle ohm reading is between Common and Start; The highest ohm reading is between Start and RunFollow the troubleshooting steps above to figure out what the compressor problem is and repair it.

R to C = lowest reading. S to C = Highest reading. S to R = middle reading. In general the two lowa should add up to the high (approx.) Nope, you messed up eddy: R to C = lowest reading.Once the wires are disconnected, you can ohm out the wires, plug and compressor as they all require an inspection. With the multimeter set to R x 1 scale (ohms), measure the resistance between the run and start wires; start and common wires; and run to common wires. There should be a measurable resistance through each set of wires.
