Dryer Is Not Blowing Hot Air
Dryer is not blowing hot air. When we have laundry issues, we expect a laundry that isn’t working at all.
This can be more difficult to determine since you could have an appliance that works in other ways but just isn’t drying clothes to your liking.
However, if your laundry usually functions except that it doesn’t get hot, this problem is a little easier to fix.
The detail of the symptoms will help you pinpoint why things aren’t operating correctly and allow you to respond more rapidly to prevent more headaches from forming down the line!
Dryer Is Not Blowing Hot Air
If your dryer drum is spinning, it means the appliance is still receiving power and the motor that turns the drum is still running.
If the heat issue is not hot enough, then this narrows down your investigation to the parts of the appliance responsible for producing, managing, and distributing that heat.
1. Thermal Fuse Issue
The thermal fuse is a way to help prevent fires in dryers. If the heat gets too hot and the thermal fuse senses that it’s getting to be unsafe, the element will shut off until it cools back down.
Once this happens, your dryer will stop heating, but you can use it as before – nothing has changed except now there is no heat.
On newer models of dryers that have this particular feature, this may cause the dryer to entirely turn off until you manually restart it when things heat back up.
A thermal fuse is essentially a one-time use heating element, meaning once it has been tripped, you will not be able to turn the heat back on until you change the fuse located near and or in the dryer’s exhaust vent.
Some models can reset thermal fuses if needed; however, they must be replaced most commonly.
It is important to remember that this was done purposely as failure to detect what caused it to trip originally will not only result in more being tripped but remain a potential fire hazard for your home.
2. Exhaust Vent Issue
If your thermal fuse was responsible for the issue, your first course of action after replacing it should be a vent hose inspection.
The flexible metal hose that attaches your dryer to the vent in your home can become blocked with a buildup of lint.
As this blocks the proper release of hot, wet air from your dryer drum, it can cause the dryer to heat up.
If the hose is blocked up, even partially, this is likely what caused the thermal fuse to blow. When cleaning out your dryer, you should also clean out your clothes dryer vent.
If there happens to be a buildup of lint in your ventilation system, it could cause a fire and should be removed, especially before continuing to use the dryer.
The most common reason for dryer fires is improper venting which causes excess lint accumulation. Take care of this issue immediately by contacting a professional or even DIY.
In certain situations where the machine flames up, one may need to address and remove the blockage from there without delay or else it will lead to damaging consequences or, worse – putting your life at risk!
3. Thermostat and Temperature Switch Issue
The thermal fuse and the thermostat do a lot to keep the temperature inside your dryer safe. If your clothes are too hot, these two parts will make sure the temperature doesn’t rise too high and cause it to overheat.
They also stop heated air from escaping while ensuring enough steam for your clothes to have a complete drying cycle.
However, if you have had a blown thermal fuse and it seems as though there may be something wrong with either one of these parts in particular, then it will likely be because one has seen damage due to overheating.
Which means that even while they are still doing their job they are unable or mislead – so check them both out if you encounter difficulties like no heat in your dryer.
A thermal sensor and a temperature switch can both be tested with a multimeter. When trying the thermostat, you should get a zero reading unless it is faulty, in which case you will get no readings at all.
To test the temperature switch, you should either read zero or infinity if the switch is working correctly. This can also be done by viewing your settings – opposite of what was initially observed when turning on the switch.
If neither happens, then it is time to replace that part! Instead of replacing your thermostat, consider replacing the temperature switch.
They are as easy to replace as removing the old one and connecting the wires to a new one, so you don’t have to worry about it causing problems with any other devices.
4. Heating Coil Issue
If the thermal fuse on your dryer is not tripped and your temperature sensor reads correctly, then you will need to replace the heating coils if they are faulty.
In most modern washer-dryers, extra wires are coiled together near the water valve, which you can check using a multimeter.
If you get zero resistance, you should replace all of these wires because they have probably worn out over time.
5. Timer Issue
It’s been said that a ticking clock talks louder than usual. A faulty timer keeps your dryer from working as it should. For example, it won’t keep moving through the cycles.
This not only can mean that you don’t get any heat, but in many cases, this condition can also result in damaging your dryer entirely.
Instead of simply spinning and spinning with no end in sight, if a bad timer is waiting for some signal, that will never come because its mechanical counterpart has stopped functioning correctly.
Conclusion
Dryer is not blowing hot air. This issue can be frustrating but you can track the issue behind it easily with the help of above discussed possibilities. We hope this articles has helped youtrack the issue.
Thank you for reading. Have a nice day!
