Checked your air pressure? If you look at the back of the heater, the pump cover will have 2 small yellow plugs. The left is a plug where you install the air guage to check the pressure. The right one adjusts the pressure at which the pump blows the fuel in.

    The photocell may be bad. It must see the proper color of flame before it will allow the heater to work. They are approximately $16.00. I purchased mine at Rural King.

I want you to inspect the fuel tank, you are looking for water that may have entered while in storage. Condensation builds from storing them and it can duplicate what you are saying here. What I did was to empty the fuel in a clean five gallon bucket and observe, fuel is lighter than water so it floats to the top water sinks to the bottom. If water is present please try to dry out the tank the best you can by soaking it up with a rag. You can siphon off the fuel just be careful not to get the water. If no water is present check to see how the igniter is positioned in conjunction to the angled spray of atomized fuel.You may have to bend it in a little closer to the fuel.

100,000 btu therm controled heater

What did you set the air pump pressure at? This is critical on heaters with Hot Surface Technology. Setting the pump pressure is always the FIRST place to start troubleshooting on these heaters.

Here are some things that can prevent ignition even though there is fuel & glow:
  1. wrong air pump pressure
  2. the nozzle is restricted & distorted not allowing fuel to contact the glowing ignitor
  3. the nozzle is worn. It should produce a cone of fog, not a spray.
  4. there is water in the tank below the fuel.
