What does a green flashing light mean?
This flashing light is indicating an error code based on the number of flashes. In your owner's manual or on the inside of the cover panel or perhaps on the furnace itself there should be a description of how to read the code and what each code means.
The furnace wouldn't kick on last night. The ok light flashes twice. It doesn't try to purge or ignite. Fan works.
Many times the air filter can be clogged and prevent airflow. If after replacing your filter your furnace continues to have issues you should hire a licensed contractor to look at the unit.

Where is the limit switch on the Achiever 90 Plus?
Owned 15 yrs but hardly used because we burned wood only backup and absence times. we started it this fall and began this. turn thermostat up and fan wants to start before it ignites. cleaned board and ckd what could. no service manual given when installed. think it may be limit switch.

Page two of the user manual identifies all the major interior parts. When it comes to working on a furnace I strongly recommend hiring a licensed contractor (due to the potential harm you can cause). Licensed contractors spend years in school and doing on the job training. So if you're unsure of your abilities, contacting a contractor is always a safe bet!
