Question about Dryers
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
I think it's a gas dryer? If so most likely it's the solenoid on the gas valve

Investigate these five areas if your dryer is not heating up:
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.
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.
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.
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.
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.

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.

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.
