MILLER/NORDYNE furnace troubles

Just moved into a new doublewide with the Nordyne MMHB-090ABHR-06. The unit had been cleaned and serviced recently.
I have noticed that I can't increase the household temp above 60-62 degrees and that the furnace was running a great deal.
Once thermostat is tripped it takes approx 30 seconds for the ignitor to light the burner( I can hear an audible click). But the burner will only stay lit for 10-15 seconds and then shut down. It will reignite again in approx 30 seconds and the burner will stay on for only 10-15 seconds. I continues to cycle like this and then eventually the blower will come on. The air from the registers is only a little warmer than room temperature.
Shouldn't the burner come on and stay on to get the air to a proper temperature?
I checked all the ground wires, the connectors running into the UTX series 1016 Hot Surface Ignitor and all were tight. There is also a red light on the 1016 at the bottom but it is not on.
I can think of nothing else to solve problem other than calling in a HVAC guy.
Any info or assistance would be much appreciated.
