flame rods, how do I know they are shot?

[Homer]

 we have been running our dryer -it's a 60" vortex- for about an hour, then all of a sudden the safety alarm went on and the dryer shut down. According to the manual, it's saying we are not getting a flame. So I have some spare flame rods here, but I'm not too sure how to tell if the old ones are shot. Will they look corroded or do they just burn out? I'm waiting to hear back from the guy we picked it up from but I'm kind of stuck at the moment. anyone have any ideas what else it could be?

Oh - one of my guys said he saw a spark next to the gas train, near one of the solenoids. We checked all the wiring and I can't find anything loose or burnt out. It blew a fuse in the main panel, we replaced it but I gotta find out what caused that spark. any ideas what to look at?




Sonny -I will try him, but I hate to bug the guy. .

Homer, try Darryl Kuebler at All-Pro Service, allprosvc1@aol.com

Ahhh, welcome to the world of gas.

I'd say try replacing the flame rod and see if it changes anything.

If it is predictable, watch the flame and see if it actually goes out before the alarm
goes off.

The flame rod is super high voltage (small amperage though) so that could be your spark.
The wire for it is pretty special stuff and needs to be in good condition.

Check everything else though; gas pressure, air filters, valves, etc.

You willl not be bugging him.  He is on the road picking up two primo Ray Pauls.

Can you take a pic of the flame rod and post it here or send it to me via email?  I know what our's looked like when it was the culprit of our dryer downtime so I can at least tell you that it looks better, the same, or worse than ours did.

[Homer]

so here's the deal. yesterday, we had a guy from the electric and gas company snooping around, looking to shut off the gas for the building next to us. . .we had the dryer running for about an hour -so we think the guy shut off our gas, and we were running on what was charged in the lines. . .so as of now,  we don't think we are getting gas in the building and I do not have anything else that runs on gas to even check. For the hell of it, we took out one of the plugs in the gas train, and we didn't smell gas, so we are pretty sure that's the culprit. I have to wait until morning to call the gas company. this whole gas thing is totally new to me so my first thought was machine went down. I never would have thought we didn't have gas, we JUST turned it on about a week ago. . .but on the good side, M&R said they are sending out my CPU tonight so the auto will be going again tomorrow. . but the dryer next to it may not work.  it took us all day to work our way down to this conclusion. . .I wonder if I can bill them back for time lost.

if this doesn't work, or isn't the problem - I'll take pics of everything and see what is going on here. thanks guys.

Homie, even our computerized residential smart meter still has a manuals shut-off valve for emergencies.
Can you see if your meter has the same? Perhaps that's all it is.

take out the rod and the spark plug and clean them with a wire brush.  Then try again.  Thats helps us on the International.

Your dryer should have a pressure gauge on or near the inlet, that'll tell you if it's
the culprit.

Turning the gas off and on to your shop is easy and should probably be common knowledge
in case of a line break before any shutoff valves.

our Raypaul has a high/low gas pressure cutoff - too much or too little pressure and it cuts the gas - there should be a reset switch somewhere...

[Homer]

yeah there are two gauges, a high and a low, and 3 shut offs. I had to adjust the pressure according to the blueprints, they were off a bit. I was talking to Todd @ Interchange and he helped me narrow down a few things. Basically what was happening is the dryer would fire up, run for an hour or two then shut itself off. Like a high temp switch was stuck or something. Then it wouldn't fire back up for a day or more. So I thought maybe a relay was shot or bad wiring or a pressure regulator went bad. I spent a day tracing all the wires, testing relays and they were all fine. I took out the flame rod and it was 7.25" long, the blueprints say to cut it down to 4.5" - so i did and it fired right up, ran all day yesterday. I know nothing about gas or burners -any of this stuff so I'm learning as I go. Thanks guys for the input, I really appreciate it. J

interchange is good people.

If you need a new dryer, I would certainly give them a shot...especially after winston stopped by here.  He had nothing but praise for their work.

kicker is I was lining up to buy one from Winston then Rick called me with this deal and yada yada, couldn't pass it by. . we'll see how good of a deal I got once we get really grinding out some shirts.

I bought a new Interchange dryer and had nothing but problems! I bought a new M&R and it is quiet and can keep up better, it also uses less gas.

The only reason people buy an Interchange is that they have a beef or don't want to buy M&R. M&R is a QUALITY dryer. I think Interchange is in a smaller building than we are! Interchange service is lacking too. They may be NICE people but we needed a dryer that would work and not shut off 4-5 times a day! When we would call them at Interchange hell the office is only there once in awhile.

[mk162]

Yeah, I had to get rid of an M&R dryer that was a POS.  The interchange dryer is an awesome dyer.  I asked the former M&R tech what dryer he would recommend and he turned me onto the interchange.  Winston paid a visit to my shop a couple weeks back and was pointing out the differences between the 2 dryers and reaffirmed my decision.

I did have the motor fail about 6 months after the dryer was installed.  They didn't even show a record of that brand motor ever being purchased.  They got me a new motor and tech to come install it.  The problem was fixed in a day...no problems since.

Homer, how was your tech support from interchange?
