Hi, Thank you for your solution reply, however I cannot find a CAD flame sensor on of the Ready Heater Parts web sites. They do mention ignitors and ignition control assembly. Are they in anyway the same thing as the CAD flame sensor ? If not, do you know who I can purchase this part through ? Thanks again, Mike

Re: heater won't refire after it warms up
If you go to mrheater.com and click on the forced air kerosene heater parts tab you need part #26865 cad cell/flame sensor, it's $2.23 the wires will be a different color and also the plug ends so just clip the wires of the old and new one and splice it to the old wires, there is no wrong way to hook them up, no hot or ground it just completes a circuit. Most parts from this company will work with any heater of comparible btu's. you can also call 800-251-0001 Hope this does it for you. I checked reddy heater and the same part lists for $18.08

1) Check wiring to Cad Cell (per wiring schematic in manual).
2) Clean Cad Cell photo cell.
a) Slide Cad Cell out of Cad Cell holder.
b) Push the photo cell out of the white rubber Cad Cell housing by
pushing on the blue and white wires.
c) Clean the photo cell with a soft cloth and rubbing alcohol.
d) Pull the photo cell back into the Cad Cell housing and reinstall into
e) Test heater.
3) If the heater still does not operate, replace Cad Cell.
4) Replace oil flame control assembly.
make sure its not a problem with the low voltage wiring to the stat. the other problem with not firing i either pressure switch not making or the flame sensor is dirty/thermal coupler (not sure which one it has)
go to Mr.heater.com and get a CAD flame sensor for any heater with the same btu output. They are all basically the same. The wires will be a different color so just splice them to you old wire harness, there is no wrong way to connect them. I just did the same thing with my dyna glo and it works perfectly. Most heater parts ar interchangeable they just have different wireing.
diesel fuel requirs a hotter spark for ignition and burns pretty dirty, better off with K1 kerosene. You could change the ignition system to a mutifuel but it's not cheap and may not mount to your current houseing but would still work. As for restarting it is one of two things: the hight heat limit control or most likely teh CAD flame sensor, both of which you can get from Mr. Heater for less than 3 bucks each. the mount for the limit control is different but you can simply remount it to your heater mount. Same thing with the flme sensor, the wires are different but you can splice the to your wire harness and it will be fine. there is no wrong way to hook them up so don't worry about ground or hot.
We had a problem keeping the pilot light to stay on, and this site recommended that it could possibly be the thermocoupler that was causing our problems also. We ordered the thermocouple, put it on,hooked it back up and it worked great! Thank you so much. ordered thermocouple from www.masterparts.net
most parts for kero heaters are interchangable. go to desatech dot com for parts. check for a reset button for your heater. if no reset, does the fan run? your unit can use one of two ignition parts. a spark generator with a spark plug or a hot surface igniter. the unit uses a cad cell flame detector. you might need to replace this.
