Question about Vulcan AUW230A Heater

Vulcan ultra 21 f11 fault code

The unit will run and then stop afte r a couple of hours. Also it was running recently and it wouldnt turn off. A service man has replaced the gas valve and remote already. All the service man wants to do is keep replacing parts in the hope it fixs the problem. There must be a way to correctly identify the exact problem without replacing parts that dont need replacing. Can anyone help pls.

My Ultra21 fired up for a while then after a few minutes the flame extinguished and the fan did its usual cool down thing, so basically we were getting warm air for a few minutes and then cold...

Try this...

Safety is you number one priority here. ( its not dangerous but its always good to be cautious)

Switch the furnaces power off from the power point to stop the heater firing up again.

Take off the cover for the circuit boards, take off the cover that covers the burner/fan etc.

You will see 2 wires from the main circuit board (one black and one grey), they feed through a grommet and feed into the burner area.

One is your igniter (i think) and the other is you flame sensor.

The one with the bent or right angle probe is the igniter.

The other is the sensor (right hand one when your viewing from the circuit board end)

Unscrew each one carefully and give it a clean with some pot scourer or steel wool etc.

I did this last night and it fixed my problem

I recently replaced the fan motor and capacitor for my condensing unit. The fan worked fine for a couple of days, but now after the unit turns on and runs for a time (minutes to an hour or so) the fan...


Yes, you either got a bad capacitor or the wrong one. As, it seems that it's overheating. When that happens it shuts OFF. After an hour of cooling, it functions again. If that's the case, in no time at all, it will fail completely.

Hope this helped you. Please let me know. Thanks.

Nothing running in refrigerator. Unplugged unit for 2 hours then pllugged back in. unit ran for about 30 seconds then stopped again


1. is light on in side when you open the door. If not check breakers or fuses.
2. Can you hear the compressor running. If not do you hear any clicking sounds.
3. If you hear clicking sounds, try putting a fan on compressor and unplug refrigerator.
4. Wait one hour.
5. plug back in. If compressor starts let it run and see if it cools, if it doesnt, call service man.
6. If it goes back to clicking, call a service man.

Car runs great then stops like its starving for gas, let it sit for couple hours then it starts up again


Check the ignition module, and fuel pressure when the trouble is present. Those are the two things on Neons that cause this problem

Fan runs but condesor not running


1. First refill the gas. Gas seems to be overcharged than the recommended value. If the gas is OK
Than,
2. There is an overload in the compressor, when it takes more then recommended amperes of current overload shuts the compressor.
Than need to change the compressor.

Compressor fridge 1956 dead!


<grin> Not under warranty any more?
Compressors have changed some since that was built but they still do the same basic job; turn a gas into a liquid so that the circulating liquid can remove heat from the unit while expanding into a gas again.
The coolant current units use is also different but serves the same purpose so I would say your old friend can be repaired.
Compressors range from ~$120 to double that (+ coolant cost) and labor is unpredictable since we don't know where you live but it is about a two-hour job. I would guesstimate between $300-$400 US - if it is quoted at lower than that, even better.
If you are in the US, check your local Better Business Bureau website for an honest service company and if more than one is listed, I'd call to get a preliminary bid on the repair. 
You might inspect the condition of the gasket since a hardened one that no longer fits flush can cost a couple of bucks a month for lost energy by running the compressor longer than should be necessary.

What could be causing this?


i service these ovens alot and my first guess the t-couple you already replaced.i wouldnt think its the valve.lp burns very dirty as you know,clean out the burner/pilot assmbely and see if this solves it.also take a look at it when its lit and see if the pilot is being pulled to the burner.let me know.also if the unit has a regulator on the back pull the vent plug and clean it up.
