If your dryer stops and starts when you put in a new belt, there could be a few potential reasons for this issue:
Incorrect installation: When installing a new belt, it's essential to ensure that it is properly aligned and correctly installed on the drum and motor pulley. If the belt is not properly seated or aligned, it may cause the dryer to stop and start intermittently.
Tension adjustment: Dryers have a tension pulley that keeps the belt tight. If the tension pulley is not adjusted correctly or is damaged, it may not maintain proper tension on the belt, leading to erratic operation.
Motor issues: The dryer's motor may have problems that are unrelated to the belt replacement. If the motor is malfunctioning or damaged, it could cause the dryer to stop and start unexpectedly.
Wiring or electrical problems: There may be issues with the electrical connections or wiring in the dryer, causing it to stop and start intermittently.
Other damaged components: When working on the dryer, it's possible that other components were inadvertently damaged or not properly reassembled during the belt replacement process, leading to the erratic behavior.
To address the problem, you should:
Double-check the belt installation to ensure it is correctly seated and aligned on the drum and motor pulley.
Examine the tension pulley to make sure it is functioning correctly and providing the right amount of tension on the belt.
Inspect the dryer's motor for any visible issues or signs of malfunction.
Check the wiring and electrical connections to ensure everything is properly connected and there are no loose or damaged wires.
If you're unsure how to proceed or if the issue persists, it's best to contact a qualified appliance repair technician to diagnose and fix the problem for you. They have the expertise and tools to identify the underlying cause and perform the necessary repairs.
