Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

Expert:  Randall replied 1 month ago.

Most shops have a board tester that can test this for you. What are the symptoms you are having?

Customer: replied 1 month ago.
Cycling not staying on changed thermostat and electric ignition still cycles
Expert:  Randall replied 1 month ago.

Is this in a furnace or water heater?

Customer: replied 1 month ago.
Hot water heater
Expert:  Randall replied 1 month ago.

How long does it run before shutting down?

Customer: replied 1 month ago.
Two minutes
Expert:  Randall replied 1 month ago.

How long has it been since you drained the water heater and flushed out the calcium deposits? If it runs for two minutes the board is fine.

Customer: replied 1 month ago.
I purchased this unit used 6 months ago never drained water heater

Then drain it out and flush it good and refill it and see if that solves this. And you might want to have the LP pressure at the tank regulator checked to be sure that the LP pressure is not too low as that can cause this.
