Question about Intertherm P3RA-060K Air Conditioner
When unit cuts on, gas ignites in chamber and heats for a minute or two, then burner and pilot light shots off, then fan turns on. I have to relight pilot light. This never seems to happen when I have the access door open to watch the pilot and ignition. I have changed the thermocouple and clean around the pilot, blew heavy dust off the fan sensors, and clean the blow. I do not have manual for this unit and I believe it is a 2002 model. It also has a small open ended copper tube that runs from the gas valve to next to pilot assymbly, not sure what it is for?
The tube is gas supply for pilot. You have to make sure the thermocouple is in the flame at least half way and make sure its tight in the gas valve. There should be a small silver plug on the gas valve near the pilot supply tube. You can pop the cap and adjust the height of the pilot flame a little. Can you tell if it has a flame rod in or above the flame? If it does You can remove it and clean it with steel wool.

SOURCE: My gas furnace that came
Try lighting all other gas appliances first. On a new setup air in the lines between the tank and the furnace takes time to bleed out before the gas reaches the pilot light.

There is probably more than one limit switch. I'll have to get a wiring diagram of this unit. See if you can follow the wires from the wires from the limit switch and see if they go to another limit switch. Also you can put a jumper wire on the red wire and white wire on the unit outside and see if ti comes on.

SOURCE: my furnace the burners light
The manual selection on the thermostat bypasses the fan relay. When in Auto, the fan relay turns on the blower. You are probably looking at replacing the circuit board. As far as the three blinks, on the reverse side of the front panel there is a wiring diagram and error code chart. It will give you a starting point where to look for a problem. The three blinks could indicate an open limit because the blower is not operating. Keep the blower on manual and let the furnace run normally until you can figure out what the problem is.

Make sure the gas valve is turned to the ON position after you had it in PILOT position. Also check the thermostat low voltage wiring @ furnace...jumper the Red & White wires to bypass the thermostat temporarily. Make sure there is 24 volts on you low voltage circuit.
