We replaced the motor on our dayton 100,000 btu torpedo..we can see the flame and everything running never heats up and then shuts it self down... if there is a quick fix will you explain ho to do it or do I need to buy new parts please help we can not get our lines thawed out with out it

Could be the Flame out sensor cutting the power to the electrics and therefore the forced air fan. It forces the heater to shut off should the flame extinguish. It might also be the temperature limit control which also turns the heater off if the internal temperature rises to an unsafe level. If either of these two possibilities the unit may need a service.

Hi,

Here are a couple of tips that I wrote that tell you how to troubleshoot a Torpedo or Reddy heater...

Check the in tank fuel filter

Check the high and low snap disk and check wall thermostat if fitted.

Hi blow heater out with air line flame sensor could be dirty check out pressure switch jump this out see if it lights

There is a flame sensor inside the burner unit. The sensor is like a photo cell that must see the light of the flame or it will tell the burner control to stop the power. You need to see if there is a soot film on the lense of the sensor and make sure the sensor is aimed straight. If the sensor is clean and aimed straight (and the problem persists) then there may be a clogged nozzle that is giving a poor flame and the sensor does not see a good flame therefore shuts down the unit. If the nozzle is at fault, then you for sure need to replace the oil filter. New nozzles are $4-8 and the size & spray angle is stamped on the nozzle. If there is still a problem, then you need to see if the pump is giving approx. 100psi pressure, then finally (the last step) would be to replace the burner control $60. Goodluck< Macgivor

Could be a bad flame sensor.
