But if not, move the refrigerator to create space for you to fit and work. As the motor runs, the contacts stay open. How it Works! However, when something is wrong, most refrigerators send out subtle signals that they are in trouble. Overload Protector: The overload protector is a simple open or closed contact device, so checking for continuity through them will tell you if they've opened. Inspect it to check for marks that show burning. All rights reserved. If this sound never happens and the temperature inside the fresh food compartment and the freezer begins to rise, then there is a good chance the start relay isn't functioning properly. He worked in the trades part-time while serving as an active firefighter. Look on the control board for signs of arcing, burnt connections, damaged foil, wear, or any other damage. The wiring may not supply the higher starting voltages and amps needed for bigger compressor motors. You are using an out of date browser. The compressor is found at the lower rear of the freezer, with the exception of the high-end, built in style refrigerator-freezers on which the compressor is usually on top. 6 What is overload protector and what is role of overload? At a minimum, the wire size should be 12 gauge. How do you know if your refrigerator overload is bad? Any inductive load when switched off, can produce electromagnetic interference (EMI). A bit of investigation finds that the compressor is starting or trying to start but only runs for a few seconds. 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. how to tell if refrigerator overload protector is bad Compressor Overload Protector Testing! (I also tested the compressor for continutity and current flows . Next, reach into the compartment and unmount the relay device from the compressors side socket. Turn down the freezer's temperature setting to see if the fridge kicks on. Newer refrigerators use solid-state starter relays. Place the probes of the multimeter between terminal 10 and terminal 11. Go to the bottom back, remove the panel over the compressor, and find the relay. If the reading you get is wrong, clean the relay and run the test again. If you notice any of these symptoms, contact a qualified appliance repair shop and make an appointment for a technician to pay your refrigerator a visit.

We are no longer supporting IE (Internet Explorer) as we strive to provide site experiences for browsers that support new web standards and security practices. Think about the job your refrigerator performs. With the probes still on the terminals, adjust the control to higher (colder) and higher settings, your reading should then change to zero, indicating that you have continuity. The black probe goes into the negative terminal on the bottom. The refrigerant is cooled before it moves through the expansion device and into the evaporator. [4] Sometimes, you may need to use a screwdriver to pry tabs open on the plastic cover to remove it from place. Before testing the compressor motor, unplug the freezer to avoid an electrical shock hazard. We have affiliate relationships with the providers (Amazon, Clickbank, etc) of the products, goods and services that are linked to on this page and may be compensated when you buy. If you see an error, try reloading the page. The start relay is located inside the same compartment with the compressor and is plugged into the back of the main device. To fix the problem of a fridge compressor tripping overload, you may have to replace the compressor. To test the overload protector of a refrigerator compressor, do the following: Disconnect the refrigerator from electric power and move the appliance. And if there is a burnt odor coming from it, replace the relay because it is damaged. Ensure that you have disconnected your appliance from the power before beginning as you will be handling electrical components. When you first plug it in, your refrigerator works continuously, twenty-four hours a day, every day. On modern refrigerators the overload relay is usually a combined part and plugs directly onto the side of the compressor. But you haven't determined whether the clicking sound is actually coming from the external relay correct? If the reading exceeds 1 ohm, replace the PTC relay. Locate and remove your overload or relay-start capacitor. Unmount the nuts securing the bottom back panel over the compressor. The power heats the sensor, increasing its resistance. Overfilling the freezer can block air vents, restrict the flow of cold air, and overtax your refrigerators condenser, which could lead to a burn out. If you have items in your cart, they will be saved for your return. Simply snap a photo, and we'll take care of the rest.

This repeated clicking is a likely signal that the start relay has failed and needs to be replaced. I bypassed it and watched it and all seems well. Each time the start relay kicks the compressor on, there is an audible click. Do not touch the terminals until you have discharged the capacitor. As such, the compressor is subject to lots of stress. However, you should understand that at some point, you may require the services of a qualified appliance technician to diagnose and repair some problems. Plus, these are the appliance repairs you dont need to call a pro for. But if you find no continuity, replace the relay. Next, find the ports marked S and M on the relays side and insert the probes. The resistance rises to the point where it eliminates the need for the starting components. And a few times, it cycles off for a few minutes before cycling on again. This type of relay has open contacts that are wired to be in series with the compressors start circuit.
