Re: reddy heater

Same problem here.....mine is an older Ready Heater with a spark plug for ignition. It was working fine then one day tried to turn it on and would not ignite. Has lots of spark and fuel, replaced but that did not work. It has got real cold here recently and I was using diesel so i switched it to K1 but nothing is working. Any help would be great.

I have a lp 75-125 reddy heater. when pluged in it no longer sparks to ignite fuel. I have the style were the ignitor is always sparking an arc.

The tranformer that sits under the motor for the igniter could be burnt out. You can use an ohmmeter to check it. I'm assuming yours has a spark plug. Make sure it isn't fouled and has a gap of .050".

I have a 165000 reddy heater.I have fuel going in,igniter is glowing ,fan is running but it will not ignite.

Now you may want to try to reposition your igniter closer to the fuel source. I have also widened the spark gap on the spark type igniters and had success. Then are you sure that the igniter is getting hot enough to ignite the fuel?

Turns on will not pump fuel photo cell works need to know how fuel gets to nozzle 75000 btu reddy heater

the fan motor has on its rear an air pump. pressure from this is fed to the fuel nozzle. the nozzle is constructed like a venturi tube. as air rushes past the venturi it creartes a suction for the fuel and expels it through the mozzle. the spark or hot surface igniter ignites the fuel. the large fan pushes the heated air and flame out the end.

Reddy Heater Doesn't fully ignite

First thing I would do is clean all of your air and fuel filters and check your lines for breaks. A lot of times they will do that if your not getting enough air to fuel mix. If it continues after that it's the CAD/ flame sensor which you can get from MR. Heater for 3 bucks they are all basically the same and I know reddy heater wants 18 for the same thing.

Please HELP

www dot desatech dot com is a parts distributor for reddy heat products. on their main page they have a short troubleshooting guide. the motor needs to provide 3.5 psi of air across the fuel nozzle to suck the fuel out of the reservoir. check your ignition source (spark plug, hot surface igniter) if the hot surface igniter is broken get a new one, if the spark plug don't spark, check the gap might be too big. see if the spark plug is grounded. poor grounds will cause intermittent sparking. check the high voltage wire for breaks in the insulation, might be shorting out to ground BEFORE the plug. gap should be 75 thousandths.
