How To Clean A Dryer Centrifugal Switch

When you press the start button on your tumble dryer and hear a humming noise coming from the engine area, it's still not time to panic. Yes, it could be a faulty motor, but it is possible that the centrifugal switch of the motor is hung.

A centrifugal dryer switch uses centrifugal force to open and close contacts in most dryer motors. When a dryer motor accelerates, the weights on the dryer motor slide out, taking pressure off the plunger on the centrifugal switch.

This allows the switch to open the contacts to the initial windings and close the heavy-duty contacts for the dryer heater.

Sometimes when a tumble dryer's motor is covered in dust, the weights hang out. The powder prevents the weights from putting pressure on the plunger of the centrifugal switch, closing the contacts to the starting winding. A tumble dryer motor cannot start with just the windings, so it will buzz. Hold down the start button long enough and it will burn the windings.

Another big problem with dust that causes the centrifugal switch to hang is that the dryer heater contacts are closed. If the timer is moved from the off position to normal drying, the heater will energize with the dryer without turning and the motor will not run. This is a fire hazard.



So how do you fix a hanging centrifugal switch in a tumble dryer?
It is actually very easy to clean a centrifugal switch in a tumble dryer. Disconnect the dryer from the electrical supply and gain access to the dryer motor. You may be lucky and have a blind access panel at the back of the dryer just behind the removable motor. The access panel is generally held in place by two screws. The good news is that it is not necessary to remove the motor from the dryer to clean the centrifugal switch. Take a vacuum cleaner that blows and completely removes dust from the motor. Return to the regular vacuum cleaner and wipe off all lint in the dryer base area. Use your fingers to slide the weights back and forth on the dryer shaft, making sure not to hit the springs. DO NOT lubricate this area as this will only attract more dust.

Refrigerator Water Dispenser Not Working

This item is a basic DIY look at a non-water dispensing refrigerator water dispenser. It is not an all-inclusive step-by-step diagnostic procedure because in this case, it is best to leave it to a professional.

If your refrigerator's water dispenser doesn't work, there are a couple of things to consider. If your ice machine is making ice, then you know that the problem is not the water supply to the refrigerator. If there was a restriction in the water line between the refrigerator and the water supply line, the ice maker could not make ice.

The water valve supplying water to the side of the water dispenser may be restricted, however, the chances of only that side being restricted are quite low. The first thing to check before you even consider the water valve on the water dispenser is the condition of the water tank inside the fresh food section. Many people are unaware that to get cold water through the water dispenser on the freezer door there must be a water tank in the fresh food section.

This tank is usually located low behind the vegetable drawers because the bottom of the fresh food section is always the coldest. And by the way, this is why the first glass of water you get from the water dispenser is generally not that cold. The waterline has to run out of the refrigerator so it doesn't freeze and out of the freezer door. There is enough water in that line to fill a glass. So if you really want cold water, always pour the first glass. The problem with the water tank located in the fresh food section is that it tends to freeze.

And if the water freezes, there is no way the water supply can pass. If you're not in a hurry, you can find out if this is the problem by placing a temperature gauge in one of the fruit and vegetable drawers and leaving it overnight. If the temperature is low, around 32 degrees, then perhaps all you have to do is warm up the fresh food section a bit to solve the problem. Once you set the controls for warmer temperature, it will take at least 24 hours for the tank to defrost if it has chunks of ice.

If you are sure that the tank is not the problem, you will need to take out the refrigerator and access the water valve that supplies water to the water dispenser. This is where you are going to need an assistant. Once you gain access to the fill valve, you can remove the electrical connections to the valve. It should be a plastic molded connector that slides immediately. With your meter set to voltage, have an assistant press the button on the dispenser to ask for water.

If you read the proper electrical voltage for your model refrigerator, and its waterline is not restricted because it is frozen or otherwise, the valve is probably faulty. However, if you don't read the voltage when your assistant presses the button, you'll probably have to call a professional appliance technician who has experience with your model refrigerator. This is because there are many switches and controls that could be faulty and that are beyond the diagnostic capabilities of most DIY homeowners. Plus, hiring a professional will save you money and hassle in the long run.

Dishwasher Leaking From Bottom Door

If you do enough service in the dishwasher sooner or later, you'll find a dishwasher that appears to be leaking from the bottom with no obvious signs of a problem.

There are many things that will cause a dishwasher to lose water and most of them are quite obvious. However, in this article, we will discuss a particular cause that is not so obvious.

Make sure you don't have an excess noise problem with the dishwasher. A dishwasher that overestimates will flood the foam at the bottom of the door along with plenty of water. To learn more about a dishwasher that is oversized, click here

Before you begin to troubleshoot a bottom leaking dishwasher, find out how long the dishwasher has been in this location. Was the dishwasher moved for any particular reason or just installed?



Sometimes, when a dishwasher is not installed properly, it could be slightly to one side of the cabinet opening. It won't be obvious until you try to slowly close the door. If the door contacts the cabinet on both sides, there is a good chance that the gasket in that area will not seal properly. When that happens, the water will bypass the gasket and run to the bottom of the dishwasher, making most people think the problem is in the pump area.

The latches on the dishwasher doors are not as strong and the gaskets on the dishwashers are not very abundant. Therefore, the slightest pull on the dishwasher door from the cabinet could cause it to flex out of the square and drip.
