    The heat participator is set from factory for general gas valves. It should be set to the amp draw of the valve it takes a very complicated method to set. I would really suspect the thermostat being bad. How old it the unit? is it loose on the wall causing it to be out of level? Is it digital or mercury?

There is no heat anticipation in the digital thermostats. The thermostat it's self is probably faulty.

Put in new Honeywell t-stat. Put new sequencers in. Heat runs for five min shuts off for 2 -5 min then back on continuously. Inside temp stays the same as set point???

What is the model number of the new thermostat? What could be happening is that the cycle rate needs to be changed or if it has a heat anticipator it may need to be adjusted.

Honeywell lr1620

I do not believe that LR1620 is a model number, you may need to find another number. Try this link to see if maybe it's your thermostat or not. The stamp LR1620 is actually on multiple thermostats. Hope this helps!
Read down the PDF file till you see the instructions on setting the heat anticipator.

Yes you can change that by change the number of cycles per hour that your t-stat looks from for youe furnace. Lower the cycles per hour number and it will increase the range.

The furnace shuts off before set temperture is reached

This could be normal. Some thermostats are designed with a heat anticipator. The anticipator takes into consideration heat that will remain within the system after the burners shut down, it anticipates the "left over" heat will be enough for the thermostat to reach it's setpoint. If it did not have this function the setpoint would be overshot.

If you are suggesting it shuts off well below the desired setpoint please clarify.

I believe if you take the outer ring off you will see a small resitance strip that is called the heat anticipator. You should see a small pointer that can be moved one direction or another This will adjust for your heat and cooling override.This will tell the furnace to shut off at the temperature you have it set at.
