Samsung gas dryer DV218AGW/XAA

[megadan66]

Have a customer who's dryer runs for a minute then blinks hE.

I have the repair manual from Samurai's stash, tells me to check air vent, no prob and the thermistor, but doesn't say what the thermistor should read.

I took a reading and it reads 553 ohms so I'm not sure if it's good or not.And if it is I'm not sure what to check next.

Thanx for the help....Dan

Anybody have any experience with these ?

Have you checked the heating element continuity?

Getting voltage to the heating element?

[megadan66]

well it's gas thermal fuse is good, ignitor is good, no voltage to ignitor, didn't check flame sensor and I hate to assume,but I think it's good. Does this thing have a relay to control the burner ? And what should the thermistor read ? But I'm assuming that's good too.Thanx for your help.

Whups! Had electric dryer on the brain.

Troubleshoot the gas burner like you would for any other gas dryer. e.g: Does the ignitor glow briefly and then click off? Is the ignitor cracked? Does the burner fire briefly and then shut off?

Thanx fer getting back so quick.do we know what that thermistor should read? The repair manual say's to check it when error hE comes up, but doesn't give a resistance guide.

[Samurai Appliance Repair Man]

Should be 10 k-ohms @77F. You sure about your resistance reading? If correct, seems like it's near-shorted.

[megadan66]

It was reading .553 in the 2k setting. That would be 553ohms right ? or do I need a lesson in reading resistance. And is the 10k the normal resistance of themistors in all dryers ?

No worries though the dryer fixed itself, went back checked the relay on the mother board, tested good and the dryer didn't shut off and give me hE. Plugged the wires that go to the burner circuit back in and walla it worked. Musta been a Korean gremlin.

Isn't it great they solder those relays right to the control board, so if they do go bad you have to replace the whole board.
