You will be taking a measurement/reading of the electrical resistance. The reading on your multimeter will tell you if the capacitor is working properly or needs to be replaced. Please Note: This procedure for testing to see if a capacitor is good is meant for appliance troubleshooting such as a refrigerator run start capacitor with only 2 leads.Be sure power is turned off to the appliance and unplugged from the wall. This needs to be done when you remove any type of capacitor from any type of appliance.
Once the appliance is unplugged, wait about 30 minutes after removing power before you pull the capacitor out. A capacitor on any appliance such as a refrigerator run start, washing machine motor, or microwave oven, can hold a lethal electrical charge. Waiting 30 minutes or longer will lessen the risk before you remove it. Take the capacitor out of the appliance making sure not to make contact with the leads. Depending on the type of appliance you are working on, you may need to discharge the power from the capacitor. Here is a step-by-step procedure for how to discharge a capacitor.NOTE: At times, some older types of capacitors will not need to be tested with a multimeter. This is because when some capacitors go bad, they will bulge out. You only need to do a quick visual check to see if this is the case. If the capacitor in your refrigerator is bulging, then it has gone bad and you will need to replace it.Once you have the capacitor out, use your multimeter to see if the capacitor is in working condition.
First, be sure to set your multimeter to ohms. Some multimeters have more settings, so to be exact somewhere over 10k and 1m ohms or select a higher setting of ohms. Use the same procedure whether you are using an analog meter or digital multimeter as you are testing for electrical resistance. Next, take the multimeter leads and put the black lead to the negative side of the capacitor and the red lead to the positive side. The writing or markings on the capacitor leads will most likely be a (+) and a (-). The (+) is obviously the positive, and the (-) is the negative. Once you have the leads on the capacitor, have a look at the meter reading. If the meter shows zero (0) and then moves slowly towards infinite, then the capacitor is working and does NOT need to be replaced. If the multimeter reading stays at zero (0) and does not move at all, then this indicates the capacitor is not working (open capacitor) and needs to be replaced. If the meter reading shows a very low resistance, the capacitor is shorted out.
If you need to replace your refrigerator capacitor, there are many available online for less.This method of testing refrigerator capacitors will work on all models of refrigerators such as GE, Whirlpool, Frigidaire, Samsung, LG, Maytag, Kenmore, and many others.WARNING – When you replace a capacitor make ABSOLUTE sure to replace it with one that is the exact same value or a higher value. DO NOT use a capacitor with a lesser value.The ohm is defined as a resistance between two points of a conductor. To read more about what an ohm is, see the Wiki page on the definition of the ohm. Here is the mathematical equation of an ohmThis method of testing a capacitor is meant for appliance capacitors such as in refrigerators. The same method above will work for almost any type of capacitor but we are focusing on repairing appliances. Please Share Our DIY Repair Help and Projects...

My garage door just hummedGaraged Door Travel, Backward and Forward, Is Now Possible Again!Beware this item is made in China. I let the unit cool and later ran a few more up and down ...Why does my garage door opener hum but the door does not move? Why does my garage door opener hum but the door does not move? There are several potential reasons for the garage door opener to hum and the door does not move. The trolley may be stuck on the stop bolt or stop tab. There may be stripped gears, a stripped rack, a bad capacitor, or motor. To prevent possible SERIOUS INJURY OR DEATH from electrocution, disconnect ALL electric and battery power (if your opener has the EverCharge standby power) BEFORE performing ANY service or maintenance. To resolve humming issues for a chain or belt drive If the garage door opener hums twice: Check the trolley and ensure it is not stuck on the stop bolt or stop tab. See How do I get the trolley off the stop bolt or stop tab?
Remove the metal cover and inspect the capacitor. Look for oil or swelling, these are telltale signs of a failed capacitor. If the capacitor is replaced and the humming has not been resolved, replace the motor. If the garage door opener hums for about 30 seconds: Ensure the door is connected to the garage door opener. Use the emergency release handle to reconnect the door. See How can I disconnect the garage door opener to manually open or close my garage door? Check the belt or chain to be sure it has not fallen off the sprocket. After re-installing the chain or belt back on to the sprocket, ensure to check your owners manual on setting the tension to the chain or belt. If the belt/chain is connected properly, remove the metal coverto inspect the gears. If you see white plastic shavings inside the unit, or the gears appear to be worn or stripped, replace the gears. If the garage door opener is a screw drive, check for a stripped rack. It is a small black piece that runs up and down the screw.
If it appears to be worn out even a little, replace the rack. If the garage door opener hums until unplugged, the receiver logic board is damaged and must be replaced. If this is a new installation, verify that the correct bolts are used to mount the rail to the chassis. If longer bolts are used, they will interfere with the operation of the motor. Make sure you are using the bolts that came already installed on the chassis. The bolts are black in color, not silver. To resolve humming issues for jackshaft operators (3800/8500) If motor hums for 1 to 2 seconds, the door may be disengaged. Pull on the red emergency cord, then try opening door manually. If motor hums for more than 2 seconds, the collar may be slipping on the jackshaft. Tighten all 6 screws on the collar then try operating the door again. For further assistance on the 3800/8500, check the LED indicator light for diagnostic codes. Answers others found helpful How do I get the trolley off the stop bolt or stop tab?
