suburban heater issues

I have a suburban heater that heats for awhile then heat goes out but fan stays running as a call for heat yet. Had it looked at while traveling and they said it is working. Left and got to destination and turned it on and did same thing. Motor problems possibly slows down after running a while then high limits?

    Suburban hi limit switches are known to have problems. Replace it first. Doug

    I bet it is the main board. The original main boards have weak solder points that cause this. I have had to put in a new board on every heater I have had. Use the dinosaur brand replacement as the solder points are higher quality.
