Question edited for clarity and typos. Question moved from Cars and Trucks category. FULL 'make model (what it is)' in all questions please, first 3 words. Generic answer - Clean the jets, check the thermostat, check gas pressure.

it is not a CAR it is a space heater, must we guess it is Kerosene and sump means fuel tank? yes most fuel heaters on earth have ignition tests (sensors) so you to hot have huge fuel fire. , SAFETY FIRST>page 3 see it? so RTM https://toyotomiusa.com/wp-content/uploads/2021/09/Laser-73-and-73ATType-M.pdf

if safety cicuit is ok check to see if voltage to ignitor if yes but doesnt glow replace

Hi,

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

Yes it does have a reset and fortunately a simple fix How do I reset my comforts zone heater? To reset the heater, simply turn power off and unplug the heater for 10 minutes until it cools down and then you may plug the heater in and restart.

Hold the Red Button for much longer than you think. It has to fully heat the thermocouple safety device. Then release VERY slowly. There are tips here https://www.google.com/search?safe=off&rlz=1C1QJDB_enCA643CA644&sxsrf=ALeKk019mViwcH7XzWSqfLTcR2JQMQz9Og%3A1614104534374&ei=1kc1YNilFquawbkP3IGz8As&q=all+pro+propane+heater+won%27t+stay+lit ..

Its the thermacouple. It's a peice that senses the heater is lit and keeps the gas valve open. They are fairly cheap to replace.

Might have a bad board or relay .
Check to see what turn the fan on because your fan should run when heater reaches a certain temperature.

Similar heaters that use diesel have to routinely cope with the dye added to untaxed fuel, ditto similar heaters that use both fuels. Unless there was an excess of dye in the fuel you used the problem was probably a coincidence. Dirt can be a big problem due to corrosion forming in the fuel tank caused by a relatively large percentage of moisture naturally in the fuel and the formation of condensation. Fuel is generally filtered through a fine gauze when the tank is filled but there is little or no filtration preventing dirt already in the tank from being picked up and finding a way into the spray head which generally jams the spinner affecting the quality of the fuel spray. Cleaning the spinner and nozzle might work for a while but only a major clean out will restore reliability until the next time. It is also wise to check and adjust the pressure of the air pump.

Your gas pressure is regulated by the gas valve .You will need a special tool to check gas pressure on the gas valve .
Make sure burners are clean ,filters and blower wheel .
A lot of time dust settle on blower wheel and make it harder to spin causing reduction on air movement

Check the thermocouple, it is a very small diameter copper wire that goes from the gas valve to the burner. Make sure it is being hit by the flame. If it is, remove it and go to a good hardware store with it and get a new one.

You might have a bad or dirty flame sensor.
Take it out and clean with sandpaper.

This sounds like a problem with your thermocouple.

Just remove the end of the thermocouple from where is goes into the gas valve and leave the end that goes into the flame in place.

Clean the end of the thermocouple connect by scraping off just a little metal from the end just about there the nut tightens the thermocouple into the gas valve. After you have exposed some new metal do the same inside the valve where the thermocouple seats into the gas valve.
Use a small pic or similar item to scrape inside the gas valve to expose some new metal there also.

Now reassemble the thermocouple into the gas valve and see if the heater works.

If this does not solve the problem you may need a new thermocouple and you can find that at www.desaparts.com
