Question about All-Pro Propane Garage Shop Heaters - All Pro SPC 125 Forced Air Propane Space Heater

Open Question

Starts, fires but won't keep lit.

I have a All Pro SPC K100 that worked great and then tonight, started and lit about half way but then went out and smoked!! I just purchased this used and have tired it few times no problem. I have took the filter out and washed it and will let it dry. I put new fuel in hopeing that helps. I have no book to guide me for trouble shooting. It will run but no heat and then will shut off. I have no idea where to stary. I notice when i took the filter panel off, that it had a couple knobs and a air port stating so much psi but i have no clue what that is all about. Any help would be great.
Thanks

You probably have a klixon/high limit popped out or failed. This video shows were it is on another heater and although yours is different they all have limit switchs thanks to ralph nader. LOL

First thing is to download the service manual.

http://www.desaparts.com/service_manuals.html

You need to make sure the filters are clean and that you are getting the proper air pump pressure.

If the units starts up and runs good and slowly goes out it will normally be due to a lack of fuel getting to the nozzle. When there is not enough fuel being delivered to the nozzle from either a clogged fuel filter of dirty air pump output filter the unit will slowly shut down from lack of fuel.

If the unit shuts down while it is running properly and the nose come is orange then you probably have a problem with a photocell or the flame out control.

If you have other questions you can contact our service department at 269-685-4125 at extension 224

SOURCE: Heater will not get fuel. It is "All Pro" Model

First check the filters such as fuel,intake and esspecially the air exhaust filter. If the exhaust filter is dirty it will restrict air flow preventing fuel delivery. You may also want to check the hoses. If they are cracked or don't fit tight it could cause an air leak which would prevent fuel delivery. Also when you check the fuel filter check to see that the fuel pickup tube is still connected. After all of this if you still have not found the problem and fixed it you will need to check the pump pressure. Check the operators manual for pump pressure specs. if they are not written on the heater side panel.

I have a spc-40 heater i can not get it to stay fired up i press the fuel button and it does lite but after 15 to 20 i release button and it goes out what do i need to do to make it work again


Ensure all your connections are tight and not leaking. I would shot off the tank using the valve on the top. Disconnect it, then re-connect it. Once connected, ensure the fan on the unit starts to turn. Then you can slowly open the valve, give it a good 4-5 turns to ensure it is open. They try the ignition sequence again.

SPC-40 wont stay lit


Problem is either the thermocouple or the thermoelectric valve. I have one of these as well with the same problem. On mine it is not the thermocouple. I have replaced the thermocoupler and still have the problem. A thermoelectric valve is $42.25 at http://www.masterheaters.com/propane/
Im looking for a cheaper part. Any suggestions?

No heat


It is either the igniter or the limit. Their is a limit mounted
at the 12 o'clock position beside the igniter. If you look at this video you will see it. Well the base of it and 2 philliphead screws that hold it anyway. LOL

Blower runs and have ignition and fuel but fire won,t stay on . all pro spc-85 construction heater.


Most likely the flame sensor. The sensor has only one wire to it and is L shaped. Unplug the heater and take some steal wool and gently clean the the sensor.

Space runs 15 seconds then stop


check in front of the flame there should be a flame proving rod which may be dirty, use steel wool to clean it so it can sense the flame, could also be a "fire eye" like a light sensor for a outdoor night light, clean the lense

Flame goes out


the most common problem is the flame sensor located just behind the fire chamber, about two inches long in a round rubber boot with two wires. you can get one from mr. heater for about 3 bucks. the wires are a different color but all you have to do is splice them to your old wires. it doesn't matter how you connect them.

I have had the same problem on a smaller unit (30,000 BTU). I remove the cover, take the thermocouple out of the burner area, and clean it until bright with either scotch brite or very fine emery cloth. The deposit on the outside prevents it from tranfering the heat to the hot end of the thermocouple and in turn to the sensor. I usuall do this once a year. The cleaning hasn't worked for me recently but the unit is 12 years old now and I will look for something else to fix.
