Roper Dryer Won’t Start. A dryer that won’t start can be alarming, particularly if it’s a Roper dryer. They are known for their high-quality products.
But sadly a non-starting dryer doesn’t necessarily mean there is something defective with it. There are tests you can do on your own using your dryer’s wiring diagram and some basic troubleshooting tools.
It could very well be due to anything from the power source or the actual fuse in your unit and the purpose of this article will help guide you through several possible solutions to find out exactly what went wrong with your Roper to make it stop working.
Roper Dryer Won’t Start
We discuss some problems with a roper dryer that won’t start here.
Drive Belt Problem
In most household dryers when the dryer drive belt breaks the motor will run but not usually the drum because there are a few different types of dryers.
Some have a switch that turns off the electricity and this is what you should look for to know if it’s broken or just stretched out.
The belt stretches over the pulleys and if this is the case, then you will need to replace it with a new one.
Switch Belt Issue
A dryer with a broken drive belt will still run, but there will be a noticeable noise as the drum will not be turning. In some dryers, however, a belt failure switch will shut off power to the dryer.
This switch can fail even when the belt is not broken, causing the power to shut off. Start the dryer and listen for a humming noise.
If you hear one then your drive belt switch is not defective and does not require replacement at this time. Using a multimeter, check for continuity in this part near your exhaust mechanism.
If it doesn’t have continuity, replace it. If your machine has a 3-way cyclone switch, as found on many roper appliances.
Faulty Drive Motor
The drive motor turns the drum and blower to exhaust air. If it overheats and burns out, replaces the belt, blower, or bearings. But if the other components are working properly but the motor is making a humming noise.
Remove the belt from the blower, then clear any obstructions and check the dust filter for debris or damage. If both are fine, and you suspect a defective motor, replace it.
Defective Start Switch
To determine if a dryer’s start switch is not working, attempt to turn it on. If the motor turns on but the dryer does not begin to operate, it is likely due to improperly installed wiring or a faulty motor that needs to be replaced.
You can test the start switch for continuity when you are troubleshooting your dryer and use a multimeter to measure electric resistance across the two terminals. If no measurable reading is registered, the switch must be replaced.
Cause Of Timer
Unfortunately, your timer is most likely defective. But before replacing it, double-check all that could be causing the issue and make sure all other components are working as intended first.
If you confirm that everything else is functional and your timer still doesn’t work, test the timer using a multimeter and consult the wiring diagram to troubleshoot your specific problem. If the timer needs replacing, replace it.
Failed Main Control Board
The main control board might be faulty, but this is rarely the case. Before replacing the main control board, check all of the other components that are commonly found to be out of order.
If you have determined that all of the other components are operating as intended (this is a rough way of testing), then replace the main control board. The control board cannot be easily tested, but one can inspect it for signs of burning or a burnt component.
Fuse Thermal Error
Dryers have thermal fuses. In case of obstruction, this safety device will prevent overheating. When tested, a thermal fuse should have continuity, meaning that there is a continuous electrical path through it.
You need to replace the blown fuse with a new one if it has been completely damaged by heat. After removing the clothes drum, place the front panel on much lower ground than usual.
It’s easier to look at the area where a person would normally work on an automobile and use tools like a ratchet handle or screwdriver to replace what needs replacing until it’s in perfect working order.
