Do you have voltage to the three tab coil ?

Expert:  Whrlp Master Tech replied 11 months ago.

And does the igniter glow when trying to light the flame?

Customer: replied 11 months ago.
from 1 to 2 120volts
Customer: replied 11 months ago.
igniter glows
Expert:  Whrlp Master Tech replied 11 months ago.

ok so you do NOT have voltage on both of the coils on the three tab coil? is that correct

Customer: replied 11 months ago.
just on 1 to 2 nothing on 2 to 3
Expert:  Whrlp Master Tech replied 11 months ago.

ok remove the power to the dryer and ohm out on the coil terminal 2 to 3 does you have continuity?

Customer: replied 11 months ago.
Expert:  Whrlp Master Tech replied 11 months ago.

Yes you do have continuity?

Customer: replied 11 months ago.
2 ohms
Expert:  Whrlp Master Tech replied 11 months ago.

and do you have an Amperage probe meter?

Customer: replied 11 months ago.
I do
Expert:  Whrlp Master Tech replied 11 months ago.

ok start the dryer and read the igniter amp draw it should be 32.8 -3.2 amps

Customer: replied 11 months ago.
I am not showing anything for amp draw.
Expert:  Whrlp Master Tech replied 11 months ago.

ok and you have the clamp around on of the igniter wires correct?

Customer: replied 11 months ago.
got another meter 4.1 amps
Expert:  Whrlp Master Tech replied 11 months ago.

OK and I see I sent wrong info should have been 2.8-3.2 not 32.8

Ok so the igniter is what feed voltage to the gas valve coils and on one coil you get no voltage so it is either the gas valve coils or you may have a broken wire inside the insulation on the harness

Customer: replied 11 months ago.
just replaced the coils today
Customer: replied 11 months ago.
I will check wirering
Expert:  Whrlp Master Tech replied 11 months ago.

ok Now you just replaced the coils today with Samsung parts? I ask because it does not show that you can purchase the coils as a separate part on the parts breakdown .

Customer: replied 11 months ago.
it is a maytag valve(###) ###-####got maytag coils for it.
Expert:  Whrlp Master Tech replied 11 months ago.

Not that I`m showing!! had the valve been replaced before?

Here is what the manufacture shows as a replacement .

Customer: replied 11 months ago.
no it has not this is what came on it . I got it new in 2011
Expert:  Whrlp Master Tech replied 11 months ago.

Does the gas valve even look like the one I send you in the link?

Customer: replied 11 months ago.
it looks the same. My valve is a Maytag . I looked up part number it is used on all makes of dryers. the wires are good, I ohmed them out. I do not know how it could be the coil if I get power on 1 to 2 and no power on 2 to 3 . The harness is removed from coil when we checked voltage. Can you please explain?
Expert:  Whrlp Master Tech replied 11 months ago.

This is an electronic controlled unit you can not remove the wires from the component when testing for voltage ,the triacs on the control board will not give you true voltage. when you do that.

Customer: replied 11 months ago.
if you wanted me to check voltage with the connector still on the coil you might have said that.
Expert:  Whrlp Master Tech replied 11 months ago.

I would have assumed by the way you talked that you knew what you were doing !

You give the opinion that you are a service tech ,

Customer: replied 11 months ago.
this is not working . the picture of the valve you sent me has coils that can be changed out. If you information does not cover my dryer than we can not work on this very well.
Expert:  Whrlp Master Tech replied 11 months ago.

I an going off of just what the manufacture supplies all parts dealers .off of the model number you have given me .

See for your self!!

Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! The attached page shows how to test the valve, igniter and radiant sensor. If all test good, the control is likely faulty.

Customer: replied 11 months ago.
I have checked all the parts you want me to check. I checked them all before I Tried you . The last Tech. had me try this also. Now you want me to check it again. Why do you two keep having me check things that I have checked. The igniter is coming on the is 120 volts to two tab coil. The three tab coil has 102 volts between 1 and 2, it has no power between 2 and 3 . The coils are new, There is no power on 2 to 3 with it plugged into coil and the same when it is unplugged. It is a coil it does not matter if the power wires are plugged in or unplugged I will get the same readings The last guy did not know Samsung do you or are you a technician for something different? So far I am not happy at all with this service. I had to pick a monthly service plan before I could even talk to anyone. I do not want this service on a monthly service plan .

It does not sound like you are going to work with me, so I will place your question back to the list. Good luck.
