| Why would my reddy heater work great as long as the top cover is removed? As soon as I put the cover back on, it dies. Has to be starving for air but I even removed the filter, same results. Any ideas? |

If you find an answer to that problem I would like to know. ------------- If you choose not to decide you still have made a choice. |

YEP....... dont know what happened.... Original Post hello folks I got a used Reddy heater R55A, that would run for anywhere from from 5 to 20 minutes then shut down. (electronic heater ignition, not spark plug) I have completely rebuilt the pump, no real wear, no visible cracks, new filter set, new nozzle, pressure set to 3.4 per label, holds steady. the only air leak I found was the hose to the tank fitting was stretched out so I trimmed it and sealed it with a zip tie which visibly improved fuel flow. After all that it runs constantly with the cover off but dies almost as soon as the lid is out back on. My research indicated dying with the hood on the almost always means the nozzle is usually the culprit, but that did not solve the issue. I replaced the filter set because of air bubbles leaking out through the cork gaskets, the new set does the exact same thing, so I figure that's probably normal and it's not a huge air leak, just enough to show up with soapy water. I've cleaned the face of the flame sensor, but that's about the only part left to replace. The tank is perfectly clean, and I tried a brand new can of fuel, the fuel filter is perfectly clean. I'm wishing I had just bought a brand new one at this point. It's single digits here and I need to replace a transmission so any help to get this thing working properly is greatly appreciated. thanks Comment------------ Have you tested the photocell? Try this: Remove photocell from heater and set voltmeter on the 1000 Ohm (RX1K) scale. Hold the lens up to a light source (80 watt light bulb, direct sunlight, etc.) with the lens of the photocell pointed toward the light source. The resistance of the meter should be low (less than 500 ohms). Blocking off the light source by putting thumb or electrical tape over opening of photocell, the resistance on the meter should be high. Replace the photocell if a change in resistance is NOT observed during the test. Also, check the breather hole in the fuel cap to make sure it is not plugged. Answer back--- YEP.......... the breather hole in the cap was plugged...

They're sensitive to air pressure in the combustion chamber. To much and they go out. I had one doing this. I had to get longer screws plus nuts an washers to make a crack along one side of the hood to bled off pressure. ------------- Learning AC...slowly |

Odd thing of to much air as I had one I used to warm engine on crawlers before starting in below zero temps and would flame out or just smoke , unless I covered air inlet area about 1/2 of opening . It would work great then but with full inlet would not heat just smoke . ------------- Faith isn't a jump in the dark. It is a walk in the light. Faith is not guessing; it is knowing something.

They are picky and each one has different quirks. what fixes one wont fix the next 10! Thats what I found on mine. The photo cell was my biggest thing to get set right. ------------- http://machinebuildersnetwork.com/ |
