Timed cycle mean dryer not on sensor dry mode. check wire connection on moisture sensor bars (i think you forget to put 2 wire connector put together). when you use other cycle dryer use moisture sensor to dry cloths so sensor not working dryer will stop in 5 minutes or so because dryer think there are no wet cloths to dry. hope this help you.

SOURCE: Inglis gas dryer heat loss

It sounds like you have an intermittent gas valve. The ignitor is calling for heat however the gas valve doesnt want to open.

Make sure you turn off the gas and unplug before replacing.

Check for leaks after you reassemble.

SOURCE: Kenmore gas dryer heats up at cycle start, then no heat for the rest of the cycle

It can be a faulty gas flame sensor that is cutting off the gas, or a faulty thermostat.

Here is a genereic diagram for a gas dryer.

There are two thermistors (thermal sensors) in this dryer; one is the outlet thermistor located on the blower housing and the other is the inlet thermistor located on the heating element housing as an integral part of the high-limit thermostat.

jahn27_197.jpg

These thermistors are negative coefficient type and monitors the dryer temperature on their locations according to their resistance which varies inversely with the temperature. The resistance drops as the temperature rises and rises as temperature drops.

One or both of the thermistors has an open connection or high resistance which makes the electronic control board thinks that the dryer temperature is low no matter how high it is. The electronic control board then doesn't cycle the heater relay and continue to turn on the heating element. The dryer temperature continues to rise and this blows the thermal fuse.

Make sure the thermistors are connected snugly. Remember that loose or open connection means high (infinite) resistance which makes the electronic control thinks of low dryer temperature. Measure the resistance of each thermistor then refer to the tables below. Replace the thermistor if the resistance reading doesn't comply with the table.

Will not get hot


If it's a gas dryer, check the thermal fuse, gas valve solenoid, igniter, element, flame sensor, high limit thermostat, or cycling thermostat.
If electric - check the heating element, thermal fuse, or thermostat.

Overall, dryers, specifically electric dryers, are very easy to work on - youtube has some great videos too.

Admiral Dryer Model #AGD4475TQ No Heat


This is very rare on a gas dryer but I have seen it. If you have already replaced all that other stuff I would say it has to be inside the timer. On one I worked on once I could remove that orange wire and the dryer would function ok so I ordered a new timer, they sent me a bad timer. Same problem. I finally got a working timer after going through a bunch of mess. That fixed it. So if all the other components are working it very well could be the timer.

No heat from tumble dryer


Hi.

If dryer is electric check for lint obstructions, check ventilation, test thermal fuse, thermistor, cycling thermostat and high limit, element and fan.

If dryer is gas check for lint obstructions, check ventilation, test thermal fuse, thermistor, cycling thermostat and high limit, igniter, coils, burner, flame sensor and fan.

I have a gas dryer, model MDG7657AWW that will not stay heated. Every time I put it on, the flame comes on for about 21 seconds & then shuts off. I replaced the igniter, hi limit thermostat, cycling t


On a gas dryer the heat normally only comes on for 30 seconds or until the drum temp reaches 160f at which time the flame is shut down by the cycling thermostat. The drum temp then starts to drop. When the drum temp reaches 105f then another blast of heat is issued for 30 more seconds.That is how they work. Put it all back together and trow a load in there.

I have a Kenmore Series 70 Dryer and I changed the thermal fuse got hot for a few minutes the model #110.74722400


The cycling thermostat must also be replaced when replacing the thermal fuse. The cycling thermostat's failure to cycle off the heating element results in overheating of the dryer which consequently blows the thermal fuse open.

Replacing only the thermal fuse should the dryer stops running and fails to start will result in its premature blowing or even the thermal cut-out (cut-off) located on the heater duct. Like the cycling thermostat, the high-limit thermostat must also be replaced once the thermal cut-out blows open. Refer to the parts diagram in the link below and look for item numbers 31(thermal cut-off), 34(hi-limit thermostat), 39(thermal fuse), and 41(cycling thermostat.

Runs but no heat has good gas flow to dryer will not heat and makes a humming sound during what should be the heating cycle


It could be several other things thermal fuse, thermal cut out, hi limit thermostat, dryer coils, heat sensor,or igniter. All of these parts are inexpensive and easy to test and replace. Here is a video at this will walk you thru the troubleshooting a gas dryer. It may be a different model but the troubleshooting will be the same.You can also enter your model # for diagrams and illustrations. All parts come with installation instructions. Not all models are available. If you need help disassembling your machine there are videos of this also for most styles.

The dryer won't get hot. is it a fuse?


you need to dismantle the dryer and check the heating element,the hi-limit switch,the cycling switch,the thermal fuse for continuity,all will have very low readings if any except the element but should show some resistance

How do I know which thermal unit is the one that shuts the dryer off when the clothes are dry? one's called a cycling thermostat, another is called a fixed thermostat and the third is called thermal...


Usually the Fixed Thermostat (also known as the High Limit Thermostat) and Thermal Cut-Out (TCO) are used in conjunction to regulate and protect the heating circuits.

The Cycling Thermostat (also know as the Internal Bias) controls the amount of heat required/desired to dry your clothes.

You need to remove the rear panel of the dryer to access the heating circuits on this model dryer. With the back panel removed, the heating circuits will be on the right hand side and the blower fan assembly is located on the left. The Hi-Limit Thermostat and TCO are located on the outside of the heater box with the Hi-Limit Thermostat mounted next to the heating element terminals and the TCO located at the opposite end of the heater box. The Cycling Thermostat is located on the blower fan housing next the Thermal Fuse. It will be the metallic round component, while the Termal Fuse will be a white plastic component.

For better clarification, you can view an exploded view diagram of your appliance at pcappliancerepair.com. If you type in your model number, all the parts I've mentioned are listed under Section 3 (Bulkhead Parts). The components are listed as follows:

Item 6 - TCO/Hi-Limit Thermostat Kit (both parts should be replaced at the same time).
Item 15 - Hi-Limit Thermostat (sold separately)
Item 23 - Thermal Fuse
Item 24 - Cycling (Internal Bias) Thermostat

If you are experiencing heating problems or longer dry times, please review the following link:

http://www.fixya.com/support/r630242-dryer_runs_but_not_heat

Pay particular attention to the section that discusses dryer ventilation. The majority of dryer heat related problems and failures are attributed to poorly installed, clogged, or kinked dryer ventilation. If you haven't had the ducting checked in a while, now may be a good time to do so.

If you have any questions, or require additional assistance, please let me know. I hope this helps you.
