Three defrost heaters, each 15 ohms are wired in parallel to a 120 volt power supply. So, if you had 2.3 ohms between Common and Start and 1.7 between Common and Run, you should have about 4 ohms between Start and Run. Otherwise, it is the water pressure. If it helps answer the question, I can borrow a clamp-on ammeter next week and take a reading. It will then trigger or shut off the compressor depending on the cold air needs of the refrigerator. If the connections are okay and there are no signs of defects, change the sensor and the fan motor. Therefore, before you can access the compressor, you will need to gain access to the rear of the refrigerator first. The other supply wire will be connected to a capacitor and to compressor terminal will be your run terminal, mostly in split unit AC the blue color wire is used for the run terminal. Like earlier stated, a repair technician should handle sensor error codes. Some leak detectors, including the INFICON Stratus, measure concentrations in PPM (parts per million). No need for expensive in-home service calls. Otherwise, the refrigerator will require a service repair. . Method 1 Accessing the Relay 1 Unplug your fridge. In some cases, we also have to watch for automatic zeroing capabilities. If it does not have continuity, then it is faulty. However, ensure the condenser coils are dry before testing the fridge. Unthread the rear access panel at the bottom of the refrigerator. It takes a lot of measurements and math to figure this all out. Mostly in some compressors in which the common terminal is on the upper side then the left side will be start and the right-hand side will run the terminal, and Danfoss compressors in which the common terminal on the downside the right side will be the start terminal and left side will be run as I have shown in the below diagram. Any number between 5.9 and 7.5 is good. So, you may not even know when the compressor starts at random intervals throughout the day. Not all resistive loads behave in this way, though. Place the testing ends of the multimeter on the short copper pipe sticking out from the compressor. I already publish a post about the start, run, and common identification guide on this blog. (note that direct wire was connected in those single phase compressor, in which the overload protector is instilled internally). Now long-press the test mode button for 3 seconds. All of this to say that Ohm's & Watt's laws are useful and accurate, but they are impacted by real under load forces in such a way that it is much more realistic to make measurements on a functioning device and work backward than to use ohms to work upwards from an ohm bench test and a voltage. To test for a short to ground, set a multimeter to the ohms scale and touch one lead to a clutch coil terminal and the other to a ground point on the compressor. Motor winding resistances of the single door direct cooled refrigerator compressor is as below:Common running = 29 ohmCommon starting =32 ohmRunning-starting = 60 ohmCan we conclude that compressor ok? Now connect one lead of the meter to the compressor common and the other connects the compressor uninsulated body place. Remember to exercise extreme caution because on a 90-degree day, the pressure in a de-energized R410A system can be approximately 275 psi and when a compressor has shorted out, the plug can overheat and become soft. If this component fails, replace it because the compressor will likely overheat. To clear the FF/rF error code, defrost the refrigerator manually. So if you are still in doubt, check the manual. In some cases, a single screw will be holding the plastic cover in place. Check the connection between the duo, and reset it if there is a need. Example - C -S = 7 Ohms. When there is a shortage of refrigerant, the compressor will work twice as hard to keep the refrigerator cool. Now if you check the compressor motor windings and do not find any problem and the still compressor did not run then change the capacitor and if still compressor not working then check the overload protector. If you need more clarification, the video below would be helpful. First, it starts from the evaporator tube. Other times, it will be several clips. Turn the air conditioning system on.
