Reddy heater 165,000 runs for approx 15 to 20 min. I unplug wait 5 min. it restarts again and runs for another 15 to 20 min. and so on ....and so on purchased approx 1 year ago

The heater has a photocell that has to see the correct flame or it will cause the heater to turn the unit off.
I would suggest checking the the pump pressure and the output filter to make sure you are getting the correct amount of pump pressure to the nozzle.

Here is a link to the actual service manual.

More than possibly a bad fan motor! if the motor isnt blowing enough air, the element will get too hot, and make it pop off!

There may be a safety thermal cutout switch that is out of whack.

Wow! Yours is the best description of a problem I have ever seen!!! Before I read the whole thing I figured you missed the pressure check as most people do but you nailed it. This is what I would try, Replace the air filter, the fuel filter, and the fuel (to make absolutely sure there is no water in the fuel) and readjust the fuel/air mixture. If that does not do it replace the cadmium cell they only cost pennies. Let me know how you make out and good luck.

PS, I have one of these so I am pretty familiar with the problems.

This a classic occurance due to low fuel in the tank.

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!
