START BY CHECKING THAT NOTHING IS IN THE VENT PIPE ON TOP OF THE FURNACE.IF THATS CLEAR,CLEAN THE FLAME SENSOR WITH STEEL WOOL.IT IS USUALLY LOCATED DIRECTLY IN THE FLAME IN FRONT OF ONE OF THE BURNERS.

Heater


It sounds like the ignitor is not working, Since the heater is not detecting a flame it goes to lockout. Check the ignitor wiring to see if it is in good shape. Sometimes the connection where the wire (from the IID) connects to the ignitor gets corroded.

It could also be the IID which makes sure the safety loop is complete before calling for heat and sending current to the ignitor. Good luck with it.

I have a bosch aquastar aq 125fx probably 9 to 10 years old it heats fine but after about year 2 it stopped working when you fire it up shortly or immediately after firing it up before. in other words it...


You either have a weak spark from your ignitor which needs replacing, a bad elec connection to the ignitor, or it needs to be repositioned nearer the burner. Check connections and try repositioning it before you install a new on.

Flame does not stay on continues flame goes on then off then on


gas dryers typically just give bursts of fire and repeat these bursts al throughout the drying process. If the dryer works at first but then fails to come back on that is the solenoids. Any other problem is due to the heat control which on older models is done by a klixon on the blower housing. these newer models use a thermister. Thermisters change in resistance with temp changes. Most of yer problems is from the 4 wire klixons. These 4 wire klixons have a bias heater inside them that warms up the bimetal. This cause it to trip prematurely for knit and permpress. Over time the bimetal gets fatigued.

Dryer is running, but heat will not turn on


There are several things that can prevent a dryer from not heating.. Unplug Power Before checking.
Electric Models
1- Power- Your dryer runs on 220volts. 110 runs the entire dryer and 110 runs just the element. Your breaker may have half tripped. Check to see if you are getting the correct amount of power by using a ohm meter. Also check the power cord for burn marks on the plugin and the cord itself.
2- The thermal fuse can prevent this from heating. The thermal fuse is a sensor on the blower housing the measures the temperature of the air. There is a cycling thermistat near the thermal fuse. If the dryer temp gets over 190-220 degrees the thermal fuse will blow to cut power to the element to prevent fire. You can test this by using a continuity tester.
3- High limit and/or thermal cutoff. These are both sensors on the heating element housing. Thermal cutoff is at the top and the high limit is near the bottom above the heating element connectors. Test these with a continuity tester.
4- Heating element- Just below the high limit on the heater housing. Test for continuity.
5- Motor- The motor has to reach a certain rpm to activate a sinfrigrial switch inside the motor. If the rpm is not reached it will not allow current to go to the element.
6- Timer- Make sure you are trying this on timed dry. Sometimes people use air fluff and forget to change it back. The timer could also not be sending current to the heater.

Gas models
1- Electric ignitor- Inside the flame tunnel inside of dryer near where gas line hooks up. Usually if it glows than it is still good but check to see if it is sending and amp signal to the heat coils.
2- Heater coils are two valves that open up when the ignitor send signal saying the ignitor can ignite the gas. Heat coils will not open to send gas if it does not receive a signal from the ignotor. They look like two round disk with two wires running from ignitor.
3- Flame sensor- Change if you change the heater coils. The flame sensor could not be detecting the flame inside so it shuts down the ignitor.
4- Motor- See above
5- Timer See above

If you have any further questions or need further assistance please feel free to comment me back.

Dryer is not heating. where is the heat sensor on DLE5001W


On a gas dryer the gas assembly is simply powered up by a sensor on the blower housing. If heat is called for from upstairs the power flows through the bimetal mounted on the blower housing. Here is a simple bi-metal: themobilian_2460.jpg
See the 4 wires? 2 of them wires operate a small heater inside the control. when it gets heated it shuts down faster for permapress and knits. Next to the control is a fuse on most models as seen here:
themobilian_2461.jpg
That fuse blows if the air temp exceeds 350f. That control thermostat at its hottest setting of cotton shuts down at 160f. It ramps back up at 105f. and continues to send power to the gas assembly till it feels 160f and then it shuts down. SOOO.. if we have a good fuse and a good thermostat 120 volts should get to the gas assembly if heat is needed. The gas assembly has a flame sensor which detects the heat bouncing off the ignitor. An ignitor to light off the gas, and a pair of holding coils. The whole gas assembly is energized at one. But them coils will not supply gas until the ignitor drops out if the circuit. To do so the flame sensor bi metal must shut down the power to the ignitor and that frees up the power to charge them coils and yank open the valve. The gas hits the ignitor and whoosh we have fire in the hole. It takes literally no time for the temp to reach 160 in the blower housing and so the power is removed from the gas assembly and the dryer tumbles onward absorbing the heat till the temp drops down to 105f and that control once again powers up the gas assembly. If your flame sensor is working and shutting down the ignitor and the heat works once or twice but quits then them solenoids are getting hot and quitting because they are old and weak. Replace em and party on.

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.

Dryer wont get hot in the am i try it it will wrk for one load then wont get hot same thing for 4 days now


I have a Whirlpool dryer with LP gas, 7 1/2 years old. It will fire up once or twice after started then the next time it is supposed to fire it will make a buzzing sound. No heat. It will not produce heat after this until it sits for awhile then the same thing, will fire once or twice then no more. I replaced the ignitor and this did not solve the problem although it did have a consistent firing for about 3 minutes immediately after I replaced the part. then it started buzzing again and would not fire anymore. The propane line doesn't appear to be the problem either since it will work initially. Also the gas water heater in the house works fine.
