If the flame does not come on it could be the igniter needs replacing. Some times if everything is set to go but if the flame does not light up then it automatically shuts down again. It is common to have to replace igniters.
This could be a dirty flane sencor of the pressure switch check hoses are tight and not spilt , try jumping out the pressure switch see if that makes it work also check air fliter is clean .
EE 2 can be caused by a couple of things but is usually a fuel issue or a flame rod problem. The circulation fan will not come on until the burner has warmed up. The combustion blower should start almost as soon as you turn the heater on. Turn the heater on and listen for the combustion blower. If it doesn\'t start, do you get an error code? If the blower started wait for the fuel pump to come on. It will start when the burner lights come on. If the fuel pump makes a loud ticking or thumping sound, it isn\'t getting any fuel. Check the fuel filter and the strainer in the fuel sump. Make sure the valve is turned off at the barrel before removing the fuel strainer. If the fuel pump is working normally, does the heater light up. If it doesn\'t, check the igniter. You can check that first if you want and have a clamp on ammeter. Place it around one of the igniter leads and you should read 2 to 4 amps when you turn the heater on. If the heater does light but then cuts off after about a minute, clean the flame rod. Unplug the heater before removing the flame rod because it may kill the circuit board if the heater is plugged in and the flame rod touches ground. Let me know what you find.
Your off on a safety. It could be the flame rollout switch and it could be a pressure switch. What happens when you try to start it? Did you shut power to unit off.
What make and model is the heater? Could be things like debris in the air switch on the blower, air in the gas line, bad flame rectification, bad ignitor, poor grounding, etc...
Look at the flame when the blower starts. Does it change?
If so there may be a hole or crack in the heat exchanger and it may need a replacement or a new heater.
Particularly look at the area and flame associated with the pilot. If this becomes more erratic or lays down more it can be from a draft caused by the blower you may need to block the air and deflect it. Or blow out the pilot burner with compressed air and retry it this usually works especially if it has a lazy pilot flame.
If this helps you please let me know and rate me as high as you can. If not please restate your problem and tell me what you have tried. I will post back asap. Thank you and good luck.
sequence of operation is just like the monitor. combustion blower comes on to purge chamber of fumes. after the delay, the solenoid pump comes on and deposits fuel to the burner mat, within 20 sec the igniter comes on, incandesces and ignites the fuel if there is no flame, the flame rod is supposed to shut down heater and go into a lockout condition until shut off or unplugged to reset. check solenoid pump first. you already know the igniter works. check the fuel filter in the fuel sump might be clogged. check the fuel sump float valve, might be stuck, supposed to hang free in the sump with needle valve open. thermostat is digital just starts and shuts down the burner and solenoid pump.
