(Figure 35). It is extremely helpful for me. If you see signs that this start relay is bad, such as your refrigerator not cooling, you'll need to replace it. Most inverter boards will repeatedly try to power up the compressor. If you now have power to the compressor, the cold control is bad. But the compressor doesn't run all the time, only during the cooling cycle. If there is power to the components, but the compressor won't start, either the compressor or starting components are bad. A defective relay will stop the compressor from starting, meaning your refrigerator won’t run and the temperature in both compartments will begin rising. Answer: If everything else on the fridge is working….. A small relay on the motherboard (main control board) may not be sending the compressor voltage. Check the voltage that GOES TO the compressor. If your refrigerator will not start, the control board could be at fault. Replace it. A starting capacitor may also be part of the overload’s assembly and becomes crucial in providing an increased starting voltage to the fridge’s compressor windings. Install the "3-in-1" using the instructions that come with it. To test for deadbreak, first unplug and remove the icemaker from the freezer compartment. Replace the defrost switch and gear sets as described in section 4-6. To check your start relay, unplug the refrigerator. Also check your wall outlet by unplugging the fridge and plugging in a portable appliance such as a blow-dryer or electric shaver. In a Whirlpool flex-tray icemaker as described in section 4-6, the defrost timer is integrated into the icemaker. If it does, replace the defrost timer. If you have interior lights in the fridge, you have power. If you're thoroughly intimidated by electricity, then call a technician. Use butt connectors, wire nuts and electrical tape. You may be able to test each starting component and replace the bad one. How to test your fridge’s cold control & temperature control with a multi-meter: After disconnecting your appliance from the power source, open your refrigerator door and locate the control. Also make sure you cover the compressor terminals with a shield; usually you can use the old plastic relay cover and just lead the wires into it. You will see a white circle, about 5/8″ in diameter (Figure 34). They aren't that expensive. In some situations, a wiring failure could be causing the problem and a repair of the Start relay wiring will fix the problem. This will give the ADC time to finish any defrost cycle it might be in, and re-enter the cooling cycle. If you see the current draw jump to say 4 amps (typical LR current in these inverter compressors) and then drop off, keep watching. A platform to learn electrical wiring, single phase, 3 phase wiring, controlling, HVAC, electrical installation, electrical diagrams, Thanks for taking the time to discuss this, I feel strongly about it and love learning more on this topic. Make sure the "3-in-1" you get is rated for the horsepower of your compressor. If you have a fridge with ADC and the lights are on, and the compressor will not start, you need to check if you're getting voltage to the compressor starting components as described in Section 5-3(b). If this does not start the compressor, make sure you leave the timer in the "run" mode for the rest of your diagnosis. If the cause of your compressor's not starting was bad starting components, it will continue to run indefinitely. Go to section 5-3(b). When you have established that power is getting to the fridge, check your controls. (See section 4-9) If you now have power to the compressor, the cold control is bad. You will hear, see and feel nothing but a fridge that's not cold. You will hear the overload in the "3-in-1" cycling (CLICK-BUZZZZ-CLICK.) Created with by OmTemplates | Distributed By Blogspot Themes, Today i am gonna to to guide you about how to fix, Some time overload burn or cut due to high current flow, this happened when the supply off and again ON in some seconds, and the. When the fridge thermostat requests more cold air, the compressor kicks on and the refrigerant becomes high-pressure, moving through the cooling coils while fans push the cool air into the fridge and freezer compartments. First, remove the old starting components. July 20, 2015. The condenser fan that is next to the compressor comes on at the same exact time as the compressor. Look at the timing gear housing on the back of the icemaker head. One or the other should show continuity. We provide the best quality of the Aircon servicing. Examine the circle closely. The clients have full satisfaction with our works team of Aircon servicing. Test for voltage at the two compressor leads. Our company team is good experienced in Aircon servicing. The buzz will be between about 5 and 30 seconds long, and it will repeat within a minute or two. If you do hear a sound, it will be something like: "CLICK-BUZZZZZZZZZZ-CLICK." Replace it. By Lyle Weischwill. However, I've found that the quickest and easiest way to diagnose this problem is to replace all three with a solid state "3-in-1" unit, or just replace all the components. If your case is the latter, you will need to get the original equipment replacement relay assembly for your fridge. If you have a fridge with a mechanical timer and you hear nothing at all, set the cold control on the coldest setting and advance the defrost timer. If your refrigerator has solid state starting components, the "3-in-1" may fit onto your fridge directly, or it may not fit at all. If it is stuck in the defrost mode, the compressor will not run. Test for continuity between the BLACK and PINK terminals and the BLACK and ORANGE terminals of the plug (see Figure 34). How to replace the compressor start relay in a top-freezer refrigerator. It might be that one of your compressor starting components is bad, or that your compressor motor is wearing or worn out. They contain circuitry that provides a little extra power to start a hard-starting compressor. It also needs help starting up each time the cooling cycle begins. Our team does their works insufficient times. Electronic controls are complex and expensive. Hello, I have an Amana Fridge #abb1927des and I'm having an issue with the compressor not starting and as a result it is not cooling. The terminating thermostat will open and stop the heater at a certain temperature, so the fridge will not continue to heat up. You can use your alligator jumpers to wire it in temporarily. Do not forget that modern overload relays are always a combined unit commonly plugged into the compressor’s side. Does the compressor start? Note that in above electrical supply problem the refrigerator will same problem and other devices cooling fan , light etc will not working too. Place a screwdriver in the advancement pinion and advance the timer manually (remember, clockwise only) about 1/4 to 3/8 of a turn. If you have ADC, jumper the cold control terminals as descibed above, and wait for 30 minutes, then check for voltage at the compressor. Then next common problem of compressor not starting is that " your fridge supply wire will be cut internally", in this case your refrigerator all machinery will not work, the cooling fan, light etc. Since the compressor is a very important part in the refrigeration system, it needs to have a working refrigerator start relay in order to work. If you don't have interior lights, check your house breaker. I have checked the compressor on its own buy temporarily shorting the start and run connections and It starts no problem, I have bypassed the thermostat and have found the compressor is still clicking so the compressor and thermostat are okay. Listen carefully to the fridge for a two or three minutes. Sub-Zero, Viking refrigerator repair in LA JOLLA. (See Figure 36) Note carefully how they came off, in case you need to re-install them. It's time to call a tech for a compressor job, or to think about getting a new fridge. How you diagnose a non-starting compressor depends much upon whether you have a mechanical defrost timer or ADC (Adaptive Defrost Controls.) You have no way of knowing which it was, or how long it will last, without some expensive tests that probably won't tell you much anyway. There is something wrong with the compressor or compressor starting components (relay or overload.)
