I have a daewoo dryer no heat with a h7 code. I replaced the coils,ignitor, checked all the thermistor n they all have continuity
SOURCE: Gas dryer not heating up
Flash, did you check the thermal fuse in the back? On a gas dryer the drum will still turn if it's blown. check out the picture and post back.
SOURCE: Dryer will not heat up when running.
hello there
Please follow this procedure I have provided below and it will tell you how to test each one ok
Hope this is very helpful
Investigate these five areas if your dryer
is not heating up:
Proper Voltage
If your dryer won't heat up, it's
possible that it is not being supplied with the proper voltage. Here are
three ways to make sure power is getting to your dryer: First, make
sure your dryer is plugged in. Next, check the circuit breaker panel to
make sure all the circuit breakers are in the correct positions.
Finally, check to make sure no fuses in your fuse panel are blown. Any
of these could explain why power is not getting to your dryer.
Heating Element
It is possible that your dryer
isn't heating because its heating element is defective. Heating elements
are irrepairable. If yours has ceased to function properly, you will
have to replace it. Open your dryer's cabinet and locate the heating
element so that you can test it.
Thermal Fuse
Another possible cause for a dryer
not heating up could be attributed to a faulty thermal fuse. Once a
dryer's thermal fuse has blown, it is no longer of any use. If your
dryer's fuse is blown, you will have to replace it. Open up your dryer's
cabinet and locate its thermal fuse so that you can test it.
Thermostat
If any of your dryer's thermostats
have become defective, they could be the reason that your dryer is not
heating. Open up your dryer's cabinet and test each of your dryer's
thermostats. If any are faulty, replace them.
Timer motor
A defective timer motor could also
cause your dryer to not heat up. Test your dryer's timer motor. If it is
no longer functioning as it should, replace either the entire motor
assembly, or just its motor.
Testimonial: "Thank you so much. Your expert advise helped me find and fix the problem with my dryer. Again thank you."
SOURCE: No heat in a Profile
The thermistor at the back of the dryer is the inlet thermistor and it has a normal resistance of around 2270 ohm at room temperature, not zero. A zero resistance means the inlet thermistor is shorted and the control board sees it as an overheating condition and does not activate the heater relay. Replace the inlet thermistor with part number WE04X10111.
The thermistor on the blower housing is the outlet thermistor and it
has a normal resistance of around 10000 ohm at room temperature. The heating is good at 17 ohms and inlet safety thermostat and the high-limit thermostat on the heater housing and the outlet safety thermostat on the blower housing must all have continuity.

Hi,
If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.
if you dryer is gas check out this gas no heat tip....
If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.
