Dryer Not Heating

dryer won't stop

Commercial dryer not heating

The parts or conditions listed below for the dryer not heating   are ordered from most to least likely to occur. Dryer repair Miami and Broward.

Cause 1 – Thermal Fuse

The thermal fuse prevents the dryer from overheating. It is located on the blower housing or at the heat source of the dryer, which would be the heating element on electric dryers or the burner on gas dryers. This fuse should be closed for continuity. In other words, it must have a continuous electrical path through it. If overheated the fuse will cease to have continuity, breaking the electrical path and blowing the fuse. You can use a multimeter to test it for continuity. However, a blown thermal fuse is oftentimes symptomatic of an obstructed exhaust vent. Make sure that you check the dryer vent after you have replaced a blown thermal fuse.This is the fist possibility if dryer not heating

Cause 2 – Gas Valve Solenoid

Oftentimes, gas-based dryers will have two or sometimes more gas valve solenoids. These solenoids are responsible for opening the gas valve and permitting gas flow to the burner. However, it can sometimes fail to do so while in the drying cycle, which causes the dryer to take a long time. To determine whether one or more of the gas solenoids have stopped working, check the igniter. If it turns on but does not ignite the gas, then that means that the gas valve solenoid is defective. If one or more of the gas valve coils are defective, we recommend replacing them as a set. This is a high possibility if dryer not heating

Cause 3 – Igniter

The igniter uses heat to ignite the gas that passes through the burner assembly. If the igniter is not functional, then the gas will fail to ignite, which will prevent the dryer from heating. To determine whether the igniter is the source of the problem, test the igniter for continuity using a multimeter. If the igniter does not have continuity, then you must replace it.

Cause 4 – Heating Element

The heating element is responsible for heating up the air prior to entering the dryer drum. If the heating element is not working, then the dryer may not heat up. To determine if the heating element is faulty, use a multimeter to test its continuity. If the heating element does not have continuity, then you must replace it.

Cause 5 – Heating Element Assembly

The assembly of the heating element heats the air as it passes through. If some other part of the assembly is defective, then the dryer may fail to heat up. If the dryer does not heat up, then it will take a long time to dry the clothes. To determine whether the heating element is faulty, test its continuity with a multimeter. If the heating element does not have continuity, then replace it.

Cause 6 – Flame Sensor

The flame sensor detects the heat of the flame on a gas dryer. If the flame sensor is not functioning properly working, then the dryer will fail to heat. You can see whether the flame sensor is defective by using a multimeter to test it for continuity at normal room temperature. If the flame sensor does not have continuity at room temperature, then it is damaged and you must replace it.

Cause 7 – Incoming Power Problem

An incoming power problem can prevent the dryer from heating. Electric dryers require two legs of 120 volts AC or 240 volts to run. Oftentimes, a single one fuse or breaker will trip, permitting the dryer to run, but not to heat. A multimeter can be used to check the fuse box or circuit breaker or to measure voltage.

Cause 8 – High Limit Thermostat

The high limit thermostat is responsible for controlling the temperature of the dryer and shutting off the burner in case the dryer overheats. If the high limit thermostat does not work properly, you can turn off the burner even if the dryer does not overheat. However, this is also uncommon. Before replacing the high limit thermostat, check all the most commonly defective parts. If you have determined that all other components are working correctly, test the thermostat with a multimeter to verify its continuity. If the thermostat does not have continuity, then replace it.

Cause 9 – Cycling Thermostat

The cycling thermostat regulates the air temperature by turning the heat on and off. If the cycle thermostat is not working, then the dryer will not heat up. This is uncommon, though. Before replacing the cycling thermostat, check all the most commonly defective parts. If you have determined that the other components are working as they should be, test the thermostat with a multimeter to verify continuity. If the thermostat does not have continuity, then replace it.

Cause 10 – Main Control Board

The main control board can sometimes become damaged, causing it to malfunction. This is, however, uncommon. Before you decide to replace it, you should check all the more commonly defective parts. If upon examination all the other components appear to be working properly, the you must replace the main control board.

Cause 11 – Timer

If the dryer is not heating, then it is possible that the timer is defective. This is also uncommon. Before you decide to replace it, you should check all the more commonly defective parts. If upon examination all the other components appear to be working properly, then test the timer with a multimeter. If the timer is defective, then you must replace it. This is a lowpossibility if dryer not heating

4 thoughts on “Dryer Not Heating

  1. Hello! I´d like to share my experience concerning my dryer not heating problem and I´d try not to be so dramatic, but I´m a great story-teller. Six months ago I bought a dryer and I was really satisfied with it until this morning when I found out that it wasn´t heating, although the tumbler was rotating and everything else seemed ok. So, I told my husband to check the voltage because to me it had something to do with low voltage, which is a common issue at our place, but I was wrong. And thinking back I realized that the last time that I used the dryer clothes weren´t as dry as they used to be, so probably that was the beginning of the problem. I thought of calling a technician but the last time I did it, it didn´t end up well for us, neither for the appliance. So, I did the only thing I´m the best at: searching on Internet, and 20 minutes and 11 wrong pages later I found this webpage. At the begging I was a little skeptical, because of my previous fails, but I began to read it and when I was about to give up because none of the first eight listed causes worked for us (my husband and my brother in law tried them all) we got to cause 9 and I told my husband to give it an opportunity, so he did it (he is so pleasing). He went to a store and he got the cycling thermostat, after replacing it we found out that the uncommon cause #9 was our problem and we finally found the solution to our dryer not heating and luckily we didn’t have to try the other causes.
    So, thanks for your well explained webpage, it saved us time and money. I was really about to lose my nerves because a week ago we had to replace the washing machine and this ¨dryer not heating issue¨ seemed serious. I was already checking my credit cards and my savings and now I think that we´d have probably found out the solution to our washing machine problem here, but that´s water under the bridge. In that occasion we called a technician and after a meticulous examination, he suggested to replace it because ¨she was definitely dead¨. Therefore, we tried a different thing with the dryer because we didn´t want another ¨death¨ in our family and it´s when this webpage story begins. I would like to say that nowadays it´s not common for a couple of amateurs (zero experience concerning machines) to read a technical webpage (several times) and to be able to decode it (translate it into easy English) and also to put it into practice (after putting a pair of insulating gloves, just in case, and starting praying that the ¨dryer not heating¨ problem wouldn´t get worse) and finally to be successful at it (from that moment we are convinced that we are a couple of gifted technicians, and that we´ve conquered the world).
    So, seriously, thank you guys for making things easier for us, I really appreciate your work!

  2. Dear site,
    I do appreciate a lot all of your very explained information, though, I believe, you are not being very considerate to people who has no actual idea about what a machine is made of since all of the reasons listed above are explained in a way too technical for people who are looking for answers over the internet.
    Let me explain myself:
    If I google “Dryer not working” I expect to find a simple answer, with simple words. Something like: “Yoo, in my hood we just give it a few knocks until it works properly again, if that doesn’t work, and you have already checked the plug try touching the thing that controls the heat, play with the buttons, ya know.
    If none of the above works, just call a technician”
    The solutions that you are providing can be read without a dictionary only by people who already have the background to understand it and probably, don’t really need a site to check what is happening to their dryer.
    Moreover, you are providing too much information. The text is very long and very heavy to read, I am not going to lie. I did not read it fully. Most of the people right now over the internet looking for these DIY stuff are millennials. We watch thirty –maximum sixty- seconds videos because more than that means we need to focus, the problem of a generation. IMAGINE READING FIVE MINUTES OF INSTRUCTIONS IN A TECHNICAL DIALECT.
    To summarise, I highly recommend you to check this instructions again and made them less of pain in the a$s for the audience that you are trying to communicate with, you know, millennial friendly, like use examples with cats or add some plumber dressed up Golden Retriever puppies pictures at the edges of the site.
    Sincerely yours,
    Abril.

     
  3. I want to thank you for the article about why a dryer could not possibly heat. I read it completely and I found it very detailing. I also had a trouble like this last summer and because of my ignorance in this issues I had to call a technician to do the repair. I do not feel guilty about it but I think if I had had some specific instructions as the ones I have found in you web my story would have had a different result, so would my wallet. So I just want to say I appreciate your comments and your help. Next time I face this kind of situation I will immediately consult your site.
