Question about Desa International RH125AT Utility Heater

1 Answer

Reddy Heater 125t won't restart on its own after first cycle.

I have a Reddy Heater 125T that starts up fine and runs until it get up to the tempiture desired. Once at that tempiture it shuts off and will not restart when the tempiture drops unless I shut it off and restart it. Upon restarting it runs great again until it gets to the desired tempiture. Any ideas?

Sounds like a bad thermostat! (A common problem with this model) replace and it should work again!

My reddy heater 125t starts fine but only runs for a couple of minutes and then shuts itself off and the red lights that says flames begins blinking. but we open the garage door about a foot and it works...


Read your manual....it will explain why and what happens when not done.Your machine ( which I have ) requires a 11" opening of fresh air in a garage. I use a fan sideways behind the machine and that seems to work without having to open the door, also helps circulate the heat at the ceiling.

REDDY HEATER 125T WON'T INGNITE


  1. Does the ignitor glow for 5 seconds when the unit is started?
  2. What is the air pump pressure reading?
These are the starting points for troubleshooting a heater that has an ingntor.

Answer these questions and maybe someone can get you started.

Won't light


Are the ignitors intact? In other words, does the element make a loop back to the ceramic portion. The purpose of the LED is to notify the user of a defective ignitor. The other possibility is a bad control board.

If the ignitor is intact, but no power coming from the board (ignitor only glows for 5 seconds), then the board is bad or the fuse is blown. You might want to test the photocell while you are at it.

You will need to locate the correct model numbers to order the correct parts. "170T" & "125T" are only part of the correct model designation.

Post back if you have further questions.
