How to fix your Universal Multiflex trash compactor when it won't stop running
A stuck foot pedal or failed momentary start switch will cause the trash compactor to run constantly.
If the trash compactor starts as soon as you close the drawer and won't stop running, unplug the trash compactor and check the foot pedal. Make sure the foot pedal pivots freely. Repair or replace the foot pedal if it's stuck in the start position.
If the foot pedal pivots freely, then you'll likely need to replace the momentary start switch because the switch is constantly supplying power to the motor.
In trash compactors that combine the power switch and momentary start switch, you'll likely need to replace the power switch if the foot pedal pivots freely and the motor runs constantly.
Tips for getting your Universal Multiflex trash compactor drawer open when it's stuck shut
Bent support rollers or a damaged trash container can bind up the drawer when opening.
Open the drawer and check the support rollers at the bottom of the trash compactor. If the support rollers don't hold the drawer high enough and the back of the drawer binds up when opening, bend the support rollers up slightly so the drawer slides out easily. Replace the support rollers if they're damaged.
Check the drawer bottom because the drawer won't open smoothly if the bottom is bent or warped. Replace the drawer if its bottom is bowed or warped.
