Does your heater use the older spark plug technology or the newer Hot Surface Ignitor (HSI) technology?

Without this critical information about all this technician can do is guess.

My best guess at this time would be either water in the fuel or a restricted fuel filter.

My best guess is that you are are connecting to your AC receptacle with an extention cord that is too small. The Reddy Heater contains a computer that will shut the unit off if it cannot pull enough amps from your service. The longer the cord the higher the loss from receptacle to unit. This loss can be reduced by increasing the size of your extention cord. I run a 100' 10/2 cord.

Hope this helps!

Check all of your air filters but most likely it's the CAD flame sensor.

SOURCE: 150,000 BTU propane Reddy Heater shuts off after ignition

Is there a frost line on your LP tank, if so you may need to replace the tank with a larger tank or refill your tank. This can happen if the tank your using is too low or too small (use 100 lb tank or greater). If there is no frost line it may be an issue with the thermocouple. The manufacturer offers a service manual and owner's manuals on there site. This should assist you... www.desatech.com Thank you

You must make sure the mist is not to close to the igniter . If it is it wont be misty enough to ignite. And make sure its in the path of the mist. If its new return it to the store.

Reddi heater 155 owners manual?

If this has a hot surface igniter, can you see it glowing? If not the igniter could be bad or the control
board for the igniter is baed.

If you are able, remover the igniter and hook it up to a 110 outlet, if it glows the problem is in the board.

If it has a board, follow the incoming power to line 1
and line 2. You will either have to splice the two leads
from the igniter into L1 and L2 or get a special spade
connector that can hold two leads on each terminal.

Plug unit in, glow coil should glow and unit should run
thats assuming you have that style of unit. Do not
attempt to do this unless you can safely perform this.

If you know of an electrician he can do this.

Igniter lites up fan kicks on and within 5 sec shuts off

Dustin, The ignitor only glows for 5 seconds, just long enough to ignite the fuel. The heater is shutting down because the photocell does not see the correct flame color.
Since you say "comes on for 5 seconds", I can only assume that there is a flame. You do not specify a lack of flame. I am also assuming that you have had the heater running this heater season and the problem just started.

YOU must find out if the problem is fuel delivery related or electronics related. Start by checking the pump pressure.

Reddy Heater will not ignite flame

Please answer the following questions. There are several folks on the board that can help but we need to know some vital information so we can get started. Answer these, if you can:
  1. Which Pro 110 do you have. We need the exact model number. Pro 110 is a series of heaters.
  2. Does the heater have a spark plug or a glowbar (HSI)?
  3. When the motor runs is it pumping fuel?
  4. When the motor runs is the spark plug firing (or glowbar glowing)?
