How to know if the relay switch on a refrigerator is bad.
A digital multimeter is essential to test a starter relay.
If your refrigerator hums loudly, dims the lights, triggered a circuit breaker or blow a fuse every time he tries to start, the problem can be a starter relay malfunction objective compressor start relay is to connect the beginning winding in parallel with the running winding to provide the additional torque required to start and disconnect the start winding after the compressor reaches the start relay operation speed are easily tested and inexpensive to replace.
Build your unloading tool capacitor appointment alligator clips of each of the connecting son the power of resistance of conductors wound 20,000 ohms Attach other crocodile clamps on the connecting son metal rods screwdrivers The purpose of the power resistance is to limit the current flow by the discharge process and avoid screwdriver tips to become welded to the terminals of the capacitor.
Pull the refrigerator away from the wall Disconnect the power cord from the power outlet locate the motor starting capacitor These capacitors are black, tubular in shape and have two terminals to a discharge end of said capacitor by pressing blades discharge homemade tool across capacitor maintain against the terminals for a few minutes to make sure that the capacitor is fully discharged to ensure that the capacitor is discharged just short the two terminals with the metal stem of a screwdriver no spark, the capacitor is fully discharged This is very important because a good start capacitor can hold full charge for weeks or even months after the refrigerator was unplugged from the wall outlet.
Remove the metal cover starter relay housing This box can be identified by the thick red son, blue and brown entering the box The lid can be held in place by a spring clip or screw the lid, pull the relay free terminals Wingding compressor.
Take a digital picture or make a sketch of how the son are connected to the relay switch Shoot the female wire connectors male side terminal on the starter relay Some of these connectors are becoming very tight with age, and you may need to use long-nose pliers to pull the free connectors with Catch the clip; do not pull on the son.
Set the function selector on your multimeter to the X1 ohms range Turn the relay upside and touch probes meters to S and M terminals on the relay for a relay good show 0000 The screen of the device Turn relay right side and repeat this test The LCD now displays OL for a good relay.
Turn the relay upside again Touch probes meters to the S and L The LCD display terminals 0000 turn right and the meter relay side should show O L.
Turn the relay upside down for a third time Connect the probe counters terminals L and M LCD displays 0000 s good for relay Turn right and read side relay should still be 0000 A relay switch that does not meet these tests is defective and must be replaced.
There are two types of relays, electromechanical and semiconductors This article concerns the electromechanical, one with the exposed coil A relay solid state can also be tested with a digital multimeter, but the test procedure is beyond the scope of this article.
