So when you spend over $30000 on a new gas dryer 2.5 years ago what would you expect in terms of support from the manufacturer in case it breaks down. How long would you be OK to wait for it to be fixed? Would you expect an approach such as "try changing this part first and see if it works then" and in case it does not " we send you another part"?
Would that be acceptable to you? Or would you rather think they should send a tech out right away?

What sort of problems? May I ask who is the manufacturer. With M&R they have had me try and figure out the problem, when we figured out the correct item they did allow me to send back wrong items and get credit minus freight. No restock fee.

I don`t want to throw out any names yet but it`s not M&R, I`m sure they would have fixed it already. We are going now into the second week without a dryer which really starts to cause problems and we are nowhere near to knowing what the exact cause is for the burner not to kick in. At one stage the manufacturer started to blame our low gas pressure even though it has not changed over the last 2 years.

Its not an acceptable practice to send "one" part to change. You would be surprised how many companies do this and the problem goes on for weeks. If that is the route a company is taking they should at least send all the parts that it could possibly be in one package instead of waiting for the next part to change to arrive. Or in your case a complete assembly to just change out and be done with it. When the problem is resolved send whats not needed back, many times the customer will purchase the parts to keep on hand anyway. But there is always the "no returns on electrical parts" issue.
If its still under warranty and the machine is down it should be a top priority to get a tech on site asap with the understanding the customer will be paying some of the techs expenses. Out of warranty as long as your willing to pay again machine down a tech should be made available if you choose.
If they think its a pressure issue a simple gauge or even a home made manometer would put it to rest quickly. If your getting good flow and gas pressure more then likely its an electrical problem, maybe in the safety circuit, pressure switch, solenoid valves.

What is the problem you are having? Chances are you may get better help here! Binkspot knows his stuff. Also if the dryer happens to be made by a company that uses Pantone 185 or so;) I have had to re do a ton of things on ours and I may be able to help also, PM me if you like.

We bought a dryer from a British Company.
Well anyway, the burner does not kick in for more then 3 seconds,then the recycle fan kicks in nd the burner will try to restart again after roughly 1 minute. Then the same happens again. Sometimes we are lucky and we get the burner to kick in and then we are good to go for the day. But honestly that takes a lot of time and I could not tell what it depends on. Now we have very low gas pressure, apparently, but that was no problem so far, the dryer was running fine for 2 years on that same pressure. The electrodes in the burner where too far apart but we have adjusted that but it did not fix the problem. They considering to send a new burner in case the next parts don`t help:(
-
I'm sorry this my be a stupid question but, have you replaced the sparkplug & ignition rod? I would assume this is the first thing they had you try, but just checking.

And yes I think its very common practice for manufacturers to try & get you to fix the problem first but, as soon as you ask for a technician that should be it & they should be scheduled to come out & fix it.

I think the speed at which a technician is dispatched would be dependent on the level of service contract you buy.....It may be that the manufacturer is just living up to the their obligations under the contract....

It could be many things.
If you have a low pressure condition existing could be the pressure switch is border line between making and breaking. When it first starts the rush of gas could cause a pressure loss momentarily and shut the system down. We are at the end of a major line, every three months they test the gas at my building for odder. When they do my pressure drop for a few min and I can hear the switch tripping out on low pressure.
It could also be a faulty or dirty fire sensor, I don't know if it uses a flame eye or rod.
Maybe a weak transformer, from what you said I assume it has electrodes instead of a spark plug? Did you adjust the electrodes because they were burnt? I would guess unless the tips were burnt and it's been running there should be no adjustment needed.
What royster said I agree with but if a machine is down the service department should make it a priority to get it resolved.

I think your dryer was actually made in China. Is it an Adelco? Just asking as your troubleshooting depends on the brand.
-
we have had same issues with probable same dryer brand. Viewing glass, UV detector, position of spark plug are things we checked and replaced. I found local gas burner expert who we call when needed. He is independent technician for bakeries, big heating burners etc. I beleive you cannot have Steve from UK help in real time manner. Many gas burners operate in similar way, our dryers are not special in any way.
-
Satronic UV detector is most likely localy available. We keep spare one. Spark plug maybe moved, less likekly broken. Glass might be dirty or
scratched.
-
this may not be it but we experience the same symptoms on our old Vortex. The only thing that solves the problem is replacing the wire that connects the spark plug to the transformer....I don't know what it is but every two months or so, we have to replace that piece of wire...

Made in the UK, CPN.

The electordes/spark plugs where kind of far apart but we moved them closer so that there is a distance of only 4mm which according to their tech is the recommended distance. Still no luck. As mentioned once in a while after lots of trying we get the burner to run but I can not tell why.
May I ask what the glass is everyone is referring to, I assume you are reffering to the viewing glass of the burner,right? How would make a difference if it is scratched or dirty?
-
Had our gas company come by as all the trouble started to check the gas pressure in our line. It`s rated at 2.17kPA which is 16.27 mm HG. As far as I know that should be enough pressure, even though one working for the company that build our dryer insists that we are having low gas pressure. Don`t know but the dryer was working very well for the last 2 years on that pressure.
The nearest tech to us is located in Australia. We hooked up with him via FaceTime so he checked the flame through the burner glass. He mentioned it looks very weak, that`s the flame before the burner kicks in proper.
-
The glass would be over the fire eye or apparently in your case a UV sensor. It detects the presence of flame in the fire box. On start up if it does not detect a fllame or while running it will shut down the system to prevent build up of gas in the chamber leading to a possible explosion.
Like Bauman said a burner is a burner and any local industrial service company for gas appliances like ovens or boilers should be able to help and or service the equipment.
What color is the flame when it does burn, should be a nice blue with maybe a little flicker of yellow or orange
-
That would be the case in the US and Europe. Here in Japan they don`t like to deal with imported equipment. It was already really complicated to get it connected by the local gas company here.

on our dryers, there is small round glass, through which UV detector is monitoring flame in burner chamber. If it gets stained readings may be too weak and burner will not be let to open valve fully and kick in main flame.
@low pressure: how long is your gas line from main line where you have pressure valve and meter? We had about 20m and had to install additional pressure valves just before dryers.
That helped because our pressure was fluctuating on low end of acceptable.

2.17 kPa is just lowest value for our dryer. We keep it at 2.3 kPa. But we have Adelco not CPN.

This is Japan, you are not allowed to install any pressure valves to the gas line. Apparently. We have roughly 13 m of gas line from the meter to the dryer, incl three 90 degree bends and a 90 degree drop.
-
gas company did it for us. these were valves with fixed pressure settings. It's not uncommon to lose some pressure on longer lines. Do you get same pressure readings on at gasmeter and on dryer?
-
Well we did ask CPN and they confirmed their dryer can run at a lower pressure then what`s supplied by our gas company. And sice it`s been working just fine for the last 2.5 years at this gas pressure.

Ok, to my relieve this issue has now been taken care off. I want to be fair towards the manufacturer of this dryer, Sanco Technologies, and mention that the problem we had was 100% of our own making. Back then as we purchased the dryer via a distributer we had not enough cash left to have someone come over to Japan from the UK and set ip up proper. Now we had their engineer over who walked me through the whole dryer set up, explained me how to take care of it proper, what to do if any issues pop up, how to change parts, replace the electrodes etc.
The dryer has been set up now perfectly, runs super quiet, is extremely cold on the outside and probably the most efficient dryer on the market.
Big thanks to the guys at Sanco in the UK. Clean Burn Dryers rock. Would highly recommend them to anyone looking to buy a new gas dryer.
