I have an all-pro 200t torpedo heater. It works perfect with no fumes at all then it just turns off and there's a light that flashes next to the light it says flame. It seems that the heater won't heat over around 60 degrees

SOURCE: torpedo heater ignites and then goes out reignites, goes out, etc.

We need to know more. Is this a kerosene or a propane fired heater?

SOURCE: All Pro 200t Will not ignite

John- the ignitor does not stay on for the duration of the running time. It only stays on for the first 5 seconds. This is long enough for the flame to ignite and perpetuate itself, assuming the fuel delivery system is up-to-par. The photocell monitors the flame color and if the flame becomes off-color then the photocell tells the control board to shut the unit down. Naturally, too rich or too lean affects flame color.

Now, I'm confused by your description "the heater cycles 3 times". Tell me more.

I'm glad to see that you checked the pump pressure. Have you used soapy water to check for air leaks all the way to the nozzle? A leak in the airline, fuel line, or a crack in the nozzle adapter will cause no fuel delivery, or reduced fuel delivery as well as reduced atomization of the fuel - all of which can cause a lack of combustion. A restricted fuel filter will cause starvation.

Eliminate all possibilities of a fuel delivery problem before you start blaming electronics because there is not much way to test the board or the photocell successfully without DESA's diagnostic tool. Unfortunately, replacement of the componants is cheaper than the tool.

SOURCE: Torpedo heater wont stay lit.

Do you have the serial number or the manufacture date? There are some design changes and I would need to know the year of manufacture to assist accurately. Usually it is a relay or the thermocouple connection that will affect the unit staying lit.

Is there a frost line on your LP tank, if so you may need to replace the tank with a larger tank or refill your tank. This can happen if the tank your using is too low or too small (use 100 lb tank or greater). If there is no frost line it may be an issue with the thermocouple. The manufacturer offers a service manual and owner's manuals on there site. This should assist you... www.desatech.com Thank you
