How does a Dryer work?

A dryer is a large barrel into which your wet laundry is loaded. It is connected by a series of belts which enables the barrel to turn. The temperature and speed are controlled by a chain of thermostats and is operated by using a timer device that can be seen on the control panel of the dryer. In order to dry the laundry, an electrical heating element is blown by means of a gas heater.

A dryer is equipped with a door switch which activates the working parts, not unless if the door is not properly closed the dryer won’t work. Numerous dryers are set up with a reset button found in the control panel. If the dryer won’t run, cool the dryer for ten minutes then push the reset button. The dryer should restart if there are no problems detected with the motor, electrical system and switches.

How to Disassemble a Dryer.

Dryer problems can be fixed using a few basic tools in just an hour. Below are some simple instructions.

 

• Take away the screws at each corner and turn over the panel up and back to expose the screws in the top panel. Remove the screws, then pull the top toward you and lift it off.
• In order to open the bottom panel, discharge the spring catches by pushing a putty knife into the hole just above them.
• With the bottom panel open, you may now eliminate the front panel by removing two screws at the top and two at the bottom.
• If your filter slides into the top of the dryer, remove the screws along side the filter slot. Again, using a putty knife, release the two spring catches located under the top panel at the front. Incline the top panel up and remove the screws that hold the front panel in place.

 

Dryer Repair Troubleshooting Guide

 

PROBLEM	REMEDY
Dryer won’t start. It might be due to door switch or simply the plunger is broken.	If the plunger is damaged, missing nor bent, replace it. But if it checks out, remove the top cabinet panel to access the door switch. (Follow the guides on how to disassemble a dryer shown above) Test the continuity of the switch by using multimeter. When it is good, test the thermal fuse found in the blower housing. If you have a gas dryer mounted with a lint filter in the door, te thermal fuse can be access by opening the bottom panel. (Follow the guides on how to disassemble a dryer shown above). If the filter slides into the top of your machine, remove the entire front panel. If you are using an electric dryer, remove the rear service panel. If continuity reading is not present after using a multimeter, do NOT simply replace it. A blown thermal fuse is an indicator that you have other serious problems such as thermostat malfunctioning or a possible clogged vent. Fix those before planning a replacement fuse.
Dryer chirps. It might be the barrel support rollers are worn out.	Replace all of them. If the noise persists, replace the tensioner roller. Clip off the old triangular roller and replace it. Wipe the beam with a clean rag with alcohol and install the new roller and keeper. Do NOT lubricate the beam.
No heat	On a gas dryer, test the thermal fuse, radiant sensor and igniter for continuity. If they fail in continuity test, replace them. In an electric dryer, disconnect the wires on to the heating element and test for continuity. If it fails, replace them. In replacing the bad heating element in an electric dryer, unscrew the retaining clip at the top of the heater box; pull out the box and remove the element retaining screw. Swap and reinstall.
Drum won’t rotate but the motor runs	Eliminate the front cabinet and lift the entire barrel out of the cabinet. Spin the tensioner roller by using your hand to check if it runs smoothly and to ensure if there are no cracks. If it fails either test, replace the tensioner by reinstalling the barrel and bind the new belt around it (ribs facing the drum). Some maybe mounted behind the motor, so in order to access it; reach your hands around the blower housing and elevate the tensioner up while you route the belt around the motor pulley.
Replacing a Dryer thermal fuse	Unplug the dryer. Detached the dryer vent hose. Eliminate the screws using a screwdriver by holding the rear panel to the dryer. Find the thermal fuse; it is usually rectangular in shape. Disconnect the wires that are attached from the thermal fuse and remember its connection to ensure it would properly function after repairing. Clean the area of the thermal fuse. See to it there are no clogs that blocks the exhaust box and around the vent hose. Replace the thermal fuse and reconnect everything to its proper position. Test the dryer. If it fails, immediately call us for abrupt help.
