 I should give up with my Speed Queen gas dryer, after changing: Coils, high limit thermostat, and also a melted roller and belt it is still not working. | ||

I had the exact same thing happen with my Kenmore gas dryer many, many years ago. The problem was the vent on the outside of the house was blocked at the very end. I had checked out everything and thought the dryer was done with. My brother in law dove into it and found that the neighbor had pushed snow up against the metal vent, bent it shut, so it couldnt exhaust right and that little bit of lint clogging the end of it made the safety things shut it off.

Thanks Wished would be that simple for me, my isssue is going ahead since October, ordered all the pieces, I had 2 change of coils etc...but I'm at starting point, of course the vent was clean and it's clean right now, new hose....it goes straight into the vent hood outside behind it, and it's clean, while disassembling I also cleaned the blower.... May be a valve assembly issue at this point... but it's too expensive to buy a 220 volt 50 Hz so I think I will just have to change dryer... | ||

Not Ignating SQ Gas Dryer Do try running the dryer with NO vent attached, if this is not the problem it may be a bad flame sensor or the gas valve itself, the 120V 60 HZ valves are the same as the 220V 50 HZ valves, just transfer the new coils to the new valve, also are you sure that you got 220 volt coils now?
And if all else fails it might be worth having an experienced technician look over the dryer as it would probably be much cheaper to fix this dryer, the problem cannot be all that expensive or difficult to fix, Good Luck , John. | ||

Thank you John Hi John, I was told by the Speed Queen dealer and Speed Queen assistance in USA (via email) that the coils I needed were the same that works with 120 volt 60 Hz and provided me with this part number:58804B & 58804A , regarding the valve indeed the repairman of the SQ dealer over here told me had to be a 50 hz and they had it on sale for 240 euros but maybe he just told me that because he wanted to sell it, the part number he told me was: 59063P ....so I could actually use a 120v 60hz? That would be good to know as I've seen many on ebay and also an universal valve that would be good for Speed Queens that is cheap, will post link later. But you say it could be even the flame sensor? I'd ask so if you maybe know if the flame sensor should be a 220 volt 50 hz, if not I will try to replace that one also...it should not cost much from USA. I will try again to run dryer with hose detached and see how does anyway, regarding repairman if he ask 240 just for the valve assembly who knows how much he will charge me for repair...unfortunately the repair costs are nit the same there're in USA... Thank you again John CLICK HERE TO GO TO kenmoreguy89's LINK on eBay | ||

Coils Coils MUST be 220 volts! Non USA 220 volt is NOT the same as ours as they dont have the neutral leg on the power supply! 110 volt coils will overheat and act intermitnly! Hope this helps. Tony | ||

mmmmhhh..... now I'm pissed, so it means that they told me an inaccuracy, I wrote to Speed Queen just to ask this, and a certain justin Deuel from Alliance told me that the 120 v coils part number:58804B & 58804A were good anyway for my 240 volt model as did the Repairman of the Speed Queen dealer near me to which they turned the email and with which I started speaking since then..... maybe he just said that because Alliance told so, he maybe just had no Idea... So please, do you maybe can help me identifying the right part number for the 220 volt coils? I started googling but no results typing "gas dryer coils 220 volt".... Thank you so much!

P,S John I detached the vent and vented it through the window for awhile.....nothing changes gas just stops getting ignited after the 3rd time, and air flow is good and strong though as it is the one coming out the hood... Then I attached it again, I did run a load and this time did beat it's record, gas got reignited for well 5 times, then no more...waited an hour and tried again, this time it got reignited for 3 times, then no more, but load was dry at that point.... tried more attempts later when empty and I noticed it does like it used before, if I shut off the gas tap, stop dryer, wait 20 mins and then open the tap and start dryer gas gets ignited.... and that is always so....while when I leave tap opened and try after 20 mins gas will never light if not after 1 to 3 hours, can't really tell why...is there an explainable technical reason for this? Thanks | ||

That's what my bad valve did. Almost always lit initially but less likely the longer it ran.
Solenoid pull decreases with temperature. A shorted turn takes out 3 turns worth of flux and the short makes temp rise faster so the whole coil becomes weaker the longer it's on. If there is really 240V across a 120V coil, temp is going to rise substantially even if the coil itself is not bad. | ||

Here is just one result from google "speed queen gas valve 240v". The price seems out of line with what I paid for mine. It may be possible to do better. But that was ~7 years ago.

I googled the part number and dicovered the one you posted is a gas valve for commercial Big size dryers, not the one for household or regular dryers... CLICK HERE TO GO TO kenmoreguy89's LINK | ||

Didn't have your model, just generic search. I get US sellers. "240v" is going to pull up commercial parts. The one you linked is also commercial, 75lb. This is a home machine, right? Are there online EU parts sellers?
I found the Whirlpool/Maytag part I bought, coil kit for both valves, $25. Some sites list that for SQ, could well be wrong. Nothing more definitive. They seldom mention voltage and only a few have photos. | ||

Yes I know, the places where I bought the coils from stated they were the same coils used on: Speed Queen, Amana, Maytag, Whirlpool. I did not even questioned the repairman of the italian SQ dealer how much they costed from them, I just asked how much was the valve (once I told him I already replaced the coils and so he diagnosed a bad valve), this for 2 main reasons, one is that I like supporting american market and economy when I can, and two I was pretty sure they were anyway cheaper to buy from USA. But if the thing Speed Queen told me about regular 120 volt coils being suitable for 220 volt machines in not correct, so after having wasted time and money, I have to call dealer again and buy from them, I asked if you maybe knew the part number for these 220/240 volt coils for the reasons I told before pretty sure I'd save finding them in the U.S.
Serial number:S9905267831
My model is a Raytheon (important company in the defense crafts etc...) marketed machine for USA Navy base and american families of american soldiers and for consulates american citizens living abroad, infact it was purchased from a marine of US Navy base here in Italy, but it's fully made by Speed Queen. I attach pic of data label of the dryer, sorry for Quality:

Those coils resemble mine and the ones I saw online. 2 pins on one, 3 on the other. I don't know how to resolve the voltage thing. The EU/240V should have its own model number different from the US version and that "should" sort it but even the tech support seems confused.
Raytheon was once a parent company for UniMac, Huebsch, Cissell, SQ. Alliance bought them. I found their online sales/support poor everywhere I looked. Since most of their machines are 30#-150#, one gets the impression their consumer product lines don't get much attention. | ||

The arcane mystery of the coils voltage has been finally explained. Everyone was correct then, I called the repairman of zone and speaking with him and questioning more I did put him in difficulty he then admitted he knows very few of these machines and just do little repairs as belts, coils and replacement liker that, so he kindly gave me the number of another more experienced and trained repairman of the Ventaria (main Speed Queen dealer in Nothern Italy), I spoke with this kind repairman and he explained me everything.... Substantially the coils are 120 volt coils, BUT this is only because valve and burner stuff works thanks to a transformer that transform electricity going to the valve, while motor is a 240/220 volt... So speaking with him he diagnosed a bad valve as well, he said that all I need is a regular valve from USA, to be on the safer side he told me to use a 50hz one (different number) but stated that even a 60hz would work anyway.... So I will try purchasing one from USA, and hope this will work...

That sounds reasonable and explains the 120/240 thing and opening enough to smell gas but not enough to light (sticky valve).
A 60Hz coil should have slightly more pull running on 50, the impedance goes down and current goes up. However, heat also goes up and temp rise is an important design parameter for solenoids. Do what the tech says. He's had his hands on them. I have only worked on 1 (mine) and without the Hz controversy. I know just enough theory to be dangerous and the math to flesh it out is over my head even if I had all the numbers. | ||
