![]() This can be caused by dust or grease getting in the space between the button and its trim.Ī gentle push or two can get the button back. When pushed in, it can get stuck in the depressed position, making it impossible to turn off the garbage disposal. While it is rare, the push button of an air switch can get jammed. If your air switch belongs to the model numbers 76703, STS-SOSN, 78251, or 74300, get it replaced immediately. This problem caused InSinkErator to call back its air switches. If water gets in your air switch, replace it with a new one. Water in the air switch can also cause the disposal to turn on and off by itself, causing possible damages to the disposal itself. If this happens, immediately turn off the power going onto the air switch and remove it from the outlet. Water getting into the power module of the air switch can cause it to overheat. When this happens, the microswitch will not work anymore. Water can get into this vacuum hose and short-circuit the micro-switch. ![]() This is a dangerous situation that can lead to fire hazards.Īir switches are operated by a vacuum hose attached to a micro-switch. There are several cases of water getting into the air switches of the garbage disposal. If the motor is burnt out, your only choice is to replace the garbage disposal. But if it is the latter case, then the disposal would hum, or its reset button would pop out when it is powered. Another possibility is that the blades of the disposal are blocked by something. It is possible that the motor of the garbage disposal is burnt out. If there is power, the problem must be with the garbage disposal. Also, test if the disposal’s power cord carries power by using a non-contact voltage tester. Use a multi-meter or a voltage tester to check if power comes from the outlet. If the garbage disposal is not working when you turned on the wall switch, the problem is with the disposal or the power from the mains. I suggest you buy a new air switch and replace the old one with it. If the garbage disposal is working, then the problem was with the power module of the air switch. Once the garbage disposal is plugged in, turn on the wall switch. ![]() Make sure you turn off the corresponding wall switch before unplugging the air switch from the power outlet. If the garbage disposal is still not working, plug it directly into the power outlet by bypassing the air switch. This should turn on the garbage disposal. Once the reset button stays in place, press the air switch button. If it is, then gently push in the reset button. Solution: Check whether the reset button on the garbage disposal is popped out. The problem could be with the garbage disposal or the electric connections inside the power module. If you hear a clicking sound from the air switch each time you push its button, it means that the air switch is working correctly. Case 2: Air switch clicks but the garbage disposal doesn’t turn on Luckily, these hoses are available in local stores, or you can solve the problem with some duct tape. Due to the leak, the hose will fail to transfer enough air pressure to operate the microswitch inside the power module. Unfortunately, you cannot buy that part alone, so buy the whole button unit and replace it.Īn air switch can also fail to work if its air-hose is leaking. Unfortunately, there is no way to repair this bellow, so you will have to replace it with a new one. If you hear a hissing sound when pushing the air switch button down, the air bellow inside this button could be damaged. ![]() If this is the case, cut the tip of the hose at half an inch length and fit it to the power module’s air hose inlet. Sometimes the air tube can fall off the unit. Solution: Check under the kitchen cabinet and make sure that the air tube is firmly connected to the power module. If you do not hear the click sound, then the problem is with its tubing or the air bellow inside the button. This click sound comes from the micro-switch that is situated inside its power module, the part which you plug into the electrical outlet under the countertop. When you push the air switch button on the countertop, you should hear a click sound. If your air switch is not working, first check whether it makes a clicking sound. So you will have to first identify the problem to fix it. There are plenty of reasons why an air switch may not be working. Case 2: Air switch clicks but the garbage disposal doesn’t turn on.
