How do I know if my overload refrigerator 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 do you bypass the overload relay on a refrigerator?
Use a flathead screwdriver to press down on the space between the relay and its casing. Then, press on the relay itself and pull it out to remove it from the refrigerator. Slide the wire from the relay so it’s accessible.
What causes a compressor to overload?
Some of the most common causes of compressor overload are directly due to neglect on your part. For example, a dirty air filter can hinder air flow, causing the system to strain to work. Electrical wiring damage can cause the unit to work inefficiently or sporadically, leading to overload on the compressor.
How do you test a switch overload?
Touch the leads on your digital multimeter to both sides of the thermal overload switch. Watch the needle on the digital multimeter display to determine if your thermal overload switch needs to be replaced. A functional thermal overload switch will cause the needle to move to “0”.
How long does it take for compressor overload to reset?
(If power is available at the compressor terminals, and no amp draw is shown, the internal overload may be open due to overheat, the unit must be cooled for the overload to reset.) This may take up to 24 hours.
Can you bypass compressor overload?
Many compressors have an internal thermal overload that cannot be bypassed. If it’s external, yes it can, but it’s extremely stupid to. If the overload isn’t working, that means it’s been in an overload condition many times before it failed, and it failed in an overload condition.
What happens when you overload a refrigerator?
Freezer Vent Blockages– When you stuff your refrigerator to its limit, you expose it to damage, which reduces its lifespan. Excessive amounts of food inside can block the flow of air from the vents, which means your condenser and refrigerator motor have to work harder to maintain the set temperature.
What does a refrigerator overload relay do?
The overload relay is a protection device used in the compressor circuit on your refrigerator. Power is applied to the compressor motor windings through the overload device, and the relay is used to add the start winding in the circuit until the compressor is at running speed.
What is a compressor overload relay?
The overload relay is also often called the ‘thermal block’ or ‘thermal relay’. This part protects your compressor from self-destructing when things go wrong. It continuously senses the current that the electric motor draws. When the current is too high for a too long time, the overload relay trips.
How to bypass start relay on refrigerator?
Using a regular screwdriver,take off the cover plate that sits over the relay system.
