Just cut and paste this link

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.

If you have one of these 125T Models- RH125AT, RHD125AT, RL125AT, RM125AT, RE125AT, M125AT, PKHD125T, TKU125T, UKU125T, RD125T

There are 3 ways to order your part.

Here is a link to a owner's manual for a RL125T ... http://12.153.20.74/manuals/110429-01C.pdf. You can find a wiring diagram on page 19. I hope this helps you.

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.

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.
