Garage heater issue

Gas heater mdl # SEP- 60A-1 becomes intermittent the colder it gets. It’ll heat to the setting on the Lux 500 thermostat at 30 +- but will not fire up regularly the colder it gets.
It’ll work for a while then not fire up on the next cycle. The only thing working on it will be the exhaust blower. It will just run on for hours. If I turn off the unit at the Lux 500 thermostat and turn it back on the exhaust fan will start up, you hear ignition spark and it will heat for a while then act up again. Help appreciated.

    Does the ignition board have an LED on it? There might be an error code displayed. In any case, start with cleaning the flame rod. Pull it out & buff it with a dollar bill. I use a $20 so I won't have to do it as often.
