Lennox Furnace burner won't stay on


I own a lennox G51MP and is nor working properly, I Called a company to see what was wrong and they said that is the Control board or the surface ignitor.
Whe I turn on the furnace, the furnace works and it reaches the temperature that I have set on my Thermostat but when it calls again for heat the induction motor stays on and it does not shut off and it gets very hot as well.
I would like to know if soembody has an Idea on what's wrong with this furnace the comoany that I called wants $1,300. to fix my furnace this is alot of money this furnace is only 7 years old, I know that is something simpler that what they are talking about also the person that came to see the furnace told that it could be the pressure switch this furnace has two.
Hopefully somebody will answer my queistion and concerns

Is it the induction motor that won't shut off and gets hot. If so the the relay on the control board is sticking on and you need a new board. It is easy to change and you can get it from cozyparts.com.
