Whether you need dryer repair for a domestic or commercial unit, there are several easy steps you can take. To begin, troubleshoot your dryer’s thermostat to determine if the problem is with the thermostat or with the overload protector. Next, check the door latch to ensure it is free from dirt and properly adjusted. If the door isn’t closing tightly, it’s likely the latch is misaligned and needs to be adjusted.
Troubleshooting A Dryer’s Thermostat
To troubleshoot a dryer’s thermostat, you must first figure out what is causing the problem. If you notice that your dryer is running too hot or too cold, you should first check the door switch. Often the door switch is hard to remove, and you may need to remove the control panel or top of the dryer to get at it. Check the wires for continuity. If you find that one of the wires is faulty, replace it.
The high-limit thermostat is the thermostat located at the rear of the dryer. Test it for continuity with a multimeter, then reassemble the dryer. If you can’t reach the thermostat, it’s likely that there’s a problem with the thermostat itself. Otherwise, check the air flow, and if there’s not enough air flow, it might be a broken blower wheel or damaged thermal fuse. If it’s not working correctly, you may need to replace the entire dryer.
Replacing The Overload Protector
One of the easiest dryer repairs is replacing the overload protector. This task only takes a few minutes. To replace the overload protector, remove the wires from the motor housing. Once you remove the wires, you must unscrew the attachment clip on the overload protector and insert the new one. After you have inserted the new overload protector, reconnect the wires. Check the overload protector again to make sure that it’s functioning properly.
You can access the overload protection switch on the top or outside of your dryer. It is usually a push button switch. These switches rarely fail, but if yours does, try replacing it. It should read zero with a volt-ohm-milliammeter set to the RX1 scale. If you can’t find the faulty switch, replace it with a new one of the same type.
Cleaning The Lint Screen
Clean the lint screen on your dryer once a month, if necessary. This will prevent buildup and can catch residue before it becomes too clogged. If the screen is removable, you may need to unscrew it and remove it. Use warm soapy water to clean the screen. Soak the screen for at least 30 minutes and gently scrub it with a soft brush. Afterward, you can use the same solution to clean the entire screen.
You can reach the lint screen at the top of the dryer through a handle. To clean it, rinse the screen and use hot water and dishwashing soap to remove any loose lint. Once the screen is clean, reinsert it and allow it to dry before you use it. Clean it thoroughly to avoid causing further damage to the dryer. You can also use a vacuum attachment to remove small clumps of lint.
Replacing The Rollers
If you suspect that the drum is causing the noise, you may need to replace the rollers. Changing the rollers can be a relatively simple repair, and the process usually costs around $100 to $150. You should first unplug the dryer from its power source. If it is not already unplugged, you should also remove the fuse or circuit breaker, if applicable. Remove the drum support rollers, which sit below the drum.
While you’re working on the rollers, you may also notice a noisy cycle. This may be a sign of worn roller axles, which are what keeps the drum spinning. Wearing roller axles can lead to the drum binding, which can cause the dryer motor to run too hard and result in it shutting down altogether. If you’re unable to identify the cause of the noise, you can replace the rollers.
Replacing The Bearing
Replacing the bearing in a dryer can be a relatively easy repair to do yourself. You can easily find the bearing on the front lip of the drum by rotating the dryer. Once you remove the bearing ring, you can easily disengage the tabs that hold the drum to the drum. Then, you can simply unscrew the two torx screws holding the drum to the bearing housing. Afterward, reinstall the drum and tighten the screws to secure it.
To replace the bearing in a dryer, first remove the drum pulley and the lint screen. This may require removing the front panel and drum. Alternatively, you can also unscrew the screw that holds the drum pulley. Once you have access to the bearing, replace the bearing with a new one. Make sure you secure the new bearing in the same way as the old one.
