Hi,it is doubtful the timer is bad,Have you tried running it with the vent off? The most likely cause is either a clogged vent or the coil valve is bad.Please keep in mind,I am not there and need your input to correctly diagnose your problem.
I havent tried running it without the vent attached.
Give that a try and see if it burns properly then.Let me know what happens.
ok. how long should i let it run?
Is it safe to operate while the rear access cover is off?
5 minuets or so.If it is burning properly it should burn for 3 min or so before the burner shuts off.
All I need you to do is disconnect the vent
ok.... running it right now...
ok,I will be right here
it appears that the burner has shut off
right away just like before?
i could see the flame for about 3 minutes and then it appeared to shut off and now has re ignited
Good,that is what it is supposed to do so far.Is it still running?
It should have relit and shut off a few times by now,has it done that?
it has cycled on and off twice since i started it. It appears that the burner has shut off again
So far so good,let it keep running for a bit.Where you are is the weather warm,cool or cold.
now i am getting relatively cool exhaust air out of the vent. burner has not re-ignited. Weather is cold. mid to upper 30's
It sounds like the coil valve,the 2 coils on the gas valve are bad.Do you have a test meter?
great,since you have cleaned it i am assuming you know how to get into it ,unplug it and get to the 2 black coils on the gas valve.remove those and unplug them.you will need to ohm out the coils.Give me a second and i will post the readings to look for.
ok. I am trying to locate the gas valve....I may have to remove another cover.
1 coil has 3 terminals,the number 1 terminal is the left one,then 2 then 3.from 1 -3 should be 550 ohm.
1 and 2 should be 1350 ohms
2 and 3 should be 1900 ohms
on the second coil 1-2 should be 1300 ohms.
If any reading varies by more than 5% or so replace the coils and you should be fine,otherwise let me know
ok. Any idea where the gas valve would be on my dryer? it looks like my flex is connected to a hard pipe that goes under the drum
what is the model number so I can look at the diagram for your dryer
its a kenmore 70 series. still looking for a specific model number
should be around the door opening
ok give me a sec to look at this
I don't see a clear picture,is your front of the dryer 1 piece or 2?
it is one piece not including the door.
pull out the lint screen,remove the 2 screws,grab the top at the front and pull towards you and raise the top.
On the front coming in from the inside are 2 more screws
that hold the front on.it sits on clips at the bottom,just pop it upwards off the clips.Be careful of the wires for the door switch
The coils sit on the gas valve on the right side,just ohm them out
If you run into a problem,Ill be right here
ill test and let u know
on the 3 terminal coil: 1-2 O.L, 2-3 1976 ohms; 1-3 565 ohms
2 terminal coil: 1-2 1314 ohms
when i measure 1-2 on the 3 term, I get a resistance reading for a second and then it reads open or OL
That is the booster coil.You need to replace the coils,part number 279834.If you have a local appliance store they should stock it for around $ 25- 30.
great! i'll try that. I can get a normal resistance reading between 1 and 2, but it doesnt seem consistant.
Those coils are the most failed part for your symptoms after a vent problem.While you are at it I would also take the time to clean the vent going outside.That is the cause of a large number of house fires that most people pay no attention to,me included
ha.... I will try that. I really appreciate your help man. You are doing a great thing in saving people money on service calls. Maybe I'll try to get on just ask. I am an electrician and rarely deal with machines from a component standpoint. thanks again.
i mean just answer
one more thing...do i have to be concerned with any seals or anything or are the coils isolated from the gas?
no,gas will not leak from there
No problem,please do not forget to rate me,be it good or bad
it will be an excellent rating. thanks again for your help.
if you run into any problems just return here and ask me
ok, i appreciate it.
