Dryer Repair usually in one visit

This is the most common dryer complaint we are called about, and most of the time the dryer itself is fine. Heat is being produced; it simply cannot carry moisture away fast enough because the vent run is restricted. Lint builds up gradually over years, so the decline is slow enough that most people never notice it starting.

There is a quick test. Start the dryer on a heat setting, go outside and put your hand over the exterior vent flap. You should feel a strong, warm flow and see the flap held open. A weak trickle, or a flap that barely lifts, means the run is obstructed. Check the flexible duct behind the machine too — if the dryer has been pushed back hard against the wall, that duct is often crushed flat, which chokes the airflow on its own. If the vent is the problem, a proper vent cleaning fixes it, and it is both cheaper than a repair and a genuine fire-risk reduction.

Similar to the previous problem, a dryer than runs but doesn’t heat up is often the result of a spent thermal fuse. In addition to keeping the exhaust vents clear of obstructions, you should always take care to clean out the lint trap after every use of your dryer. A dryer repair technician will be able to tell you if there is any blockage in your ventilation, if the machine is being frequently overloaded, or if the thermal fuse was previously activated and needs to be replaced.

Beyond the thermal fuse, a dryer not heating up is sometimes symptomatic of the heating element itself not working properly. A heating element assembly, which includes the heating element itself, thermal fuses, thermostat, and other related components, is what’s responsible for heating the air that dries your clothes. This process is impeded by any lint or debris on the element, or if it’s in contact with the rest of the dryer. The heating element is an electrical component full of coils, which can sometimes break over time with normal use of your dryer. Due to the risk of electric shock when working on a heating element replacement, we advise against a DIY repair for this one. A qualified technician will know a faulty heating element when they see one, and will be able to safely and effectively replace it in order to get your appliance back online.

If your dryer simply isn’t starting, there’s a good chance there’s a problem with your thermal fuse. These handy little devices were made mandatory for all electric dryers in the 1980s, in order to reduce the risk of fires. If the temperature of your dryer exhaust climbs too high, it activates the thermal fuse, which will shut off the dryer. This acts a safe-guard for faulty dryers, and helps to keep you safe. However, it may be activated when the machine is still at a normal temperature, causing the dryer to either not turn on at all. This is because a thermal fuse is only designed to work one time, and must be replaced afterwards. It’s also possible for a fuse to simply wear out over time, even if it was never tripped by excessive temperatures.

One other cause of this issue we sometimes see is a worn out drive pulley. If the drive belt doesn’t have the correct amount of tension on it, tension which is applied by the pulley, the drum will not spin during the cycle, even if the dryer is heating up as normal.

If your dryer is making strange noises, or causing low-level seismic activity in your home, there could be a problem with the drive set. The drive set is made up of a few components, which are responsible for the mechanical operation of the unit. The parts of a drive set in most tumble dryers are:

• Drive belt - A piece connected to the dryer’s drive motor, which is responsible for turning the drum.
• Drum support rollers - The mechanism that sits underneath the drum, allowing it to spin on top. This is usually the source of any strange noises in your dryer - a scraping or squealing when it becomes worn out, and a loud thumping when it develops a flat spot.
• Drive pulley - Also known as a dryer belt tension pulley wheel, this component maintains tension on the drive belt, allowing the drum to spin.
  
  

A technician will take a look at these components, and figure out where replacements and repairs are necessary. Once they’re replaced, you’ll finally get some peace and quiet when running your dryer.

Like a dishwasher that doesn’t wash dishes, or a fridge that doesn’t keep things cold, it’s especially frustrating when your home appliance fails at its one express purpose. There are a number of reasons why clothes may be coming out of a dryer cycle still wet. One cause could be that you’re overestimating the capacity of your dryer, and overfilling it. If the drum is completely packed, the warm air will not be able to properly circulate, resulting in a tight ball of damp clothes at the end of the cycle. If you’re still experiencing this problem, even with a regular-sized load, it could be a problem with your ventilation.

A good way to test this is to find your exterior dryer exhaust outlet, which is a small vent on the outside of your home. Turn the dryer on, and then head out to the vent. Feel the air coming out of it—if it’s moving very slowly, or isn’t particularly warm, it’s likely there’s some kind of blockage. If it’s not a ventilation issue, it could mean something’s wrong with your dryer’s heating element assembly. If you suspect a heating element trouble, be sure to call a professional rather than attempting a DIY solution, as doing so can be an electrical or fire hazard.

All modern dryers have a cycle thermostat, which maintains the temperature of the drum and regulates it so it doesn’t overheat. If your dryer is shutting off mid-way into its cycle, the thermostat may be on the fritz. Although this problem is annoying, it’s certainly better than the alternative, which is your dryer getting hotter and hotter until the clothes inside are scorched. Either way, your thermostat should be replaced.

When a dryer runs for ten or fifteen minutes and then stops, it is usually overheating and protecting itself. The cycling thermostat and the high-limit thermostat both cut power when the drum gets too hot, and the usual reason they are tripping is that hot air cannot escape — a lint-packed vent, a crushed flexible duct behind the machine, or a blocked exterior flap. The dryer is working correctly; the ducting is not.

If the vent is genuinely clear, the next suspects are the thermostat itself, a failing motor cutting out on thermal overload, or a blocked lint screen housing. A dryer that stops and will not restart until it has cooled for half an hour is the classic overheating pattern. A dryer that stops at exactly the same point every cycle, cold, is more likely a timer or control board fault. Either way, running it repeatedly while it overheats is how lint fires start, so it is worth stopping until the cause is known.

A motor that hums while the drum sits still almost always means the belt has snapped. The belt wraps the drum and drives it from a pulley on the motor; when it breaks, the motor spins freely and the drum does nothing. The giveaway is that the drum turns far too easily by hand, with none of the usual resistance.

If the belt is intact, the next candidates are a seized idler pulley, worn drum rollers or support bearings that have stiffened to the point the motor cannot overcome them, or a failed motor start winding. These parts are inexpensive and commonly replaced together, since a belt that snapped usually did so because something else was adding drag. Running the dryer repeatedly while it hums will burn out the motor, which turns a small repair into a much larger one.

Stop the dryer and unplug it. A burning smell is one of the few appliance symptoms that deserves an immediate reaction rather than one more load. Most often it is lint that has escaped past the screen and settled on the heating element, where it scorches — and lint ignites readily.

The smell can also come from a belt slipping against a seized drum or pulley, which produces a sharper rubber odour, or from a failing motor, which smells more electrical. All three need looking at before the machine runs again. This is also the point to be honest about maintenance: clearing the lint screen every load helps, but it does not reach the lint that accumulates in the housing and the duct run, which is where the real risk sits. If the dryer has never had its vent cleared, that is the place to start.
