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... Thank you

SOURCE: I have a Reddy Pro 115 BTU kerosene heater the fan

When you say that the fan starts then stops I assume you also mean that the burner starts and stops. If this is correct and the unit is more than a couple of years old you probably need to change the filter in the back and set the pump pressure. Both the filters and the gauges to set the pressure can be found at along with a good explanation as to why you need the gauges. The pressure is set by bleed air pressure and must be exactly 3.5 psig. The gauge is the only accurate way to do it. The filters clog and change the pressure. When the difference is enough the unit will not run. Now with that said there are several other things which you should check. Check the fuel tank for water. Remove any you find. Remove the cover on the right side as you look at the unit from the front and remove the circuit board. Check for cracked connections. If you find any resolder them and reattach the board. That should take care of the unit and get you back to making heat. Let me know if you need anything else.


Thanks for using FixYa

SOURCE: reddy heater won't stay going there are two

Those screws are: 1. the one with the hole in it is a relief valve to allow excess air to escape. 2. the solid plug is to be removed and a low pressure gauge inserted.

Then, you adjust the air pump pressure to factory specs. If not properly set the heater will not function properly.

115,000 btu reddy heater, 5 hrs used in sprayfoam-grinding environment. stopped working. when plugged in, only hums for a few seconds, then stops. how can i fix that?

First, remove the top cover. Inspect for a varmint nest. If clear, manually spin the fan. If it does not you either have a broken rotor that is binding or you have a bad bearing.

If it spins freely, apply power- see if the motor runs with the top cover removed.
If YES, replace the top cover. Its possible that the top is binding the fan.
If NO, the start capacitor is defective. The cap on R115 is internal and is not servicable.

Is there supposed to be flame coming around the cone of a 115,000 btu reddy forced air kerosne heater?

no. the flame should be behind the cone. If it passes the cone, this means that there is too much air. simply turn the air pressure screw until the flame no longer comes beyond the cone.

My reddy heater 115 pro starts, but shuts off after about 5 seconds of running , i replaced the filters and nozzle about 2 years ago

Here is a service manual:

If the flames actually starts but the unit shuts off after 5 seconds you need to check the pump cover on your heater to make sure you have no cracks in the rear cover.
This could be from low pump pressure but most often this problem is caused from a defective control board.

I have a 100,000 btu reddy heater, and every time I turn it on, it runs for about 5 minutes, then stops, then I have to push the reset button and start it again. Can you tell me where to start? thanx

If it actually ignites and burns but shuts off either the flame sensor is bad (or dirty) or the control is bad. I would verify the flame sensor is clean and had good electrical connections to the controller for starters.

Heater will come on for about 4 seconds then shut off. I have a 115 BTU kerosene Reddy Heater.

Removed filter and blew out a tiny piece of debris. Didnt think that would be enough to do any harm. Put the filter back in and it started up and runs great now.

Reddy heater 115,000 btu heater runs for about ten minutes then shuts off does this model have a thermostat or carb that might need adjusting????

A heater with this problem is probably the hardest to determine the cause. There is no carb orn thermostat to adj. If it uses a spark plug ignitor I would check the plug gap and make sure it is at an angle to the nozzle. If it has Hot Surface Ignition this will not be the problem. I would then check the fuel filter in the dip tube in the tank and the pump pressure. I should be about 4.5 psi. I would also remove the nozzle and replace it or at least blow it out backwards withlcompressed air to clean it. If all these items fail to correct the problem I would replace the flame sensor. Let me know what you find out or if you have any questions.
