Before you call a technician to have your dryer repaired, maybe you will be surprised to learn that you can also do many repairs all by yourself.

The tools you will need depends on the repair but generally, you will most likely to use the most common tools you might already have such as a cordless drill, pliers, Phillips head screwdriver, putty knife, vacuum and shop light. You might need to buy a hex nut driver set to open panels.  If you are planning to do-it-yourself, be sure to unplug first before repairing. However, reaching out dryer repair is actually a good choice if you reach the dead end after few attempts of fixing it by yourself. 

If the dryer won’t start, check plug, cord, and receptacle because of dryer’s high voltage draw that the cord and peripheral items may become melted. Also, check for door actuator and door switch, in order for a dryer to start, both doors must be working. These are easy to find items and simple to replace.     

When the dryer is properly venting, you must go outside and feel damp air going out of the vent. If not, Check the vent if the flaps are not working, clear with your fingers or suck vent with a vacuum. You may have a rigid metal or aluminum foil vent tube from the dryer leading to the wall. Remove at two points and clear out the vent. Also, the lint may be clogged inside the dryer. Clean it with special devices such as Lint Lizard or Lint Eater attach to your vacuum. The dryer lint filter must be cleaned after every load and replace the filter if it’s broken.   

Diagnose the problem of your dryer by identifying the noise. Squeaking noise means that drum roller bearings don’t operate as they should be. They should be either need replacement or lubrication. These bearings look like small rubber wheels that are located inside the machine and that you will require to open the dryer at the top and then slide the drum forward so that you can access the bearings. High-pitched squealing noise means your idler pulley will need to be replaced. It is a spring-loaded arm which regulates the tightness of the drum belt.  If it is too loose or too tight, friction causes the squealing.     

Thumping Noise means dryer drum rollers might have flattened. It won’t spin smoothly when the drum rotates. When the round drum hit a flat area, it will result to a thumping sound. You must replace the rollers because they cannot be repaired. Screeching noise like the sound of metal on metal means your dryer glides might be worn or damaged. It is a small part made of plastic that acts as a guide for the drum so it will move on the rollers. Glides will sooner or later wear down and when this happens, remove the top of the dryer and the front bulkhead so that you can access the glides. Glides can’t be repaired, you must replace them entirely.
