20 Most Recent All-Pro SPC-85 Utility Heater Questions & Answers

Check the thermocouple, it is a very small diameter copper wire that goes from the gas valve to the burner. Make sure it is being hit by the flame. If it is, remove it and go to a good hardware store with it and get a new one.

This sounds like a problem with your thermocouple.

Just remove the end of the thermocouple from where is goes into the gas valve and leave the end that goes into the flame in place.

Clean the end of the thermocouple connect by scraping off just a little metal from the end just about there the nut tightens the thermocouple into the gas valve. After you have exposed some new metal do the same inside the valve where the thermocouple seats into the gas valve.
Use a small pic or similar item to scrape inside the gas valve to expose some new metal there also.

Now reassemble the thermocouple into the gas valve and see if the heater works.

this unit like most has a heat switch and a thermal coupler they work to gather jump the switch if it runs then its the switch if it doesn't then its the thermal coupler flame should hit the coupler and turn red loose wire on switch has happened before to

try holding down the button for 15 to 20 seconds and then let go ( this will let the system heat up to the proper temp ),, if it still will not stay lit then the thermal coupling is bad and needs to be replaced.

Is the fan coming on when you press the start button? If not, that's the problem. Or it may be inadequate gas pressure. These are just 2 of the most common issues. So, I have included a link to your Owners Manual, that you can download and print for future reference. Please pay close attention to the Trouble Shooting Guide part of the Owners Manual.

Try cleaning the photo eye flame sensor. It is the black rubber boot close to the burner. Remove it and you can see the sensor down inside. Clean it with a soft cloth or a cotton swab and some alcohol. Also check the air line for cracks and check for tightness where the air line connects to the fan motor and the fuel nozzle. If the hose is stretched there, try trimming a little off the end so it will fit tighter. Check the fuel line for the same thing where it connects to the fuel filter and fuel nozzle. Let me know what you find and don't forget to rate the answer.

This indicates you have a bad thermocouple. It's the copper probe that goes down to the flame. You may be able to pick up one at a good hardware store such as Ace.

asimfq,

The most likely area for your problem is the thermocouple or relay. All -Pro and Reddy Heat are made by the same company Desa. I have a tip at http://www.fixya.com/support/r4258201-fix_gas_reddy_heaters_will_not_continue which should explain the problem, how to solve it and where to get the parts.

ayama794,

I have a tip at http://www.fixya.com/support/r4258201-fix_gas_reddy_heaters_will_not_continue which should help solve your problem. It is written for a reddy heater but reddy heat, all pro and dyna glo are all the same units.

Most hardware stores carry them if not try Johnstone supply

Most of these parts can be purchased thru Grainger if there is one close to you, if they do not have it they can usually locate the parts for you. They are a little pricy but they get the job done for me.
