ROLLOUT SWITCH OPEN, COLEMAN EVCON FURNACE
Reset the switch. Check the heat exchanger thoroughly for blockages, cracks or holes. Check induced draft motor for proper operation. Check flue pipe and chimney for obstructions.
Gas furnace
If it only lights for a few seconds you most likely have a dirty flame sensor. Remove the sensor polish it with some emery cloth or very fine sand paper. reinsert. problem should be solved.
What size blower motor for package unit
Look at the nameplate data on the blower motor itself. If it is an older motor, you will need the horsepower hp, the rpm, the amp draw, and the size of capacitor. Always change the capacitor when installing a new motor.
If it is a newer motor (ECM) you will most likely have to get a repair guy to get the motor and have it programmed properly at the dealer for your type of air handler.

You will need a 4 in 1 tool and new valve cores sold at most supply houses. It screws onto the service connection and the rod pushes in to unscrew the valve core. Once the core is loose, allow the pressure to push rod out, shut the 90 degree valve and unscrew the push rod, the valve core can easily be changed out for a new one by reversing steps. While your at it, get new valve caps with good orings to replace the old caps.
Furnace start stop cycle
On properly sized furnaces there are a few controls to look at. Check the settings of the fan switch. If these are unchanged then there may be a reason the furnace is shutting off due to poor air flow and resulting high temperature. Check filter and verify air flow is good. It may be possible that a safety switch is failing and intermittently on and off. Are all the covers securely in place and hitting any safety switches? If not seated properly the cover may loosen when the fan runs and the switch shut off the unit. There is often a flame roll out switch that could have been strained. Lastly, has the thermostat been working long? Thermostats have internal heaters to stop the furnace which is called a heating anticipator. If the thermostat is near a heat source (heat duct, refrigerator, oven, person, hot water pipe), worn out, anticipator is set wrong (older electric thermostats have adjustable settings) or covered (yes, I have seen some covered) then the free room air cannot measure correctly and the thermostat cannot control what it cannot accurately measure. Of all these possibilities I would start with the thermostat and proper furnace air flow, second check the fan/high limit switch and third go component by component through the wiring diagram looking for defects in each component. If available follow the manufacturer's troubleshooting guide.
