Fan wont shaut off - RTO PasLode 900420 Impulse Framing Nailer

The thermostat for the fan is shorted out

Make sure that the fan is 12 DC Volts.. If that is 12 DC volts?... you can connect that fan to power supply of your desktop wired color (+)yellow and ( -)black. If its doesnt work... that fan is defective.

Some very basic points first....have you checked and replaced the fuel filter ? These often clog over time and require replacing at service intervals. Is there a water separator in the fuel system and if so have you drained it ? Have you tried running the engine from another fuel source ? I have known fuel pipes to break down internally and cause restrictions to the flow of fuel from tank to engine. If the engine starts and runs then dies it is almost certainly going to be fuel supply causing the issue.

first check the fuse for the blower fan. if ok check if there is current going to the fan plug on top of the passenger kick panel or behind the glove compartment if there is current change the blower fan and the fan resistor next to it.

I would disconnect the fan connector and use contact cleaner to clean the connection. Usually corrosion. Also fan might be going bad (Common Problem).

is this the blower motor fan for you heating and A/C or the cooling fan cooling fans have a relay blower fans are fused but controlled from switches inside as well as fuses

!st off, do you mean the indoor unit does nothing period as wont run? or wont cool?if it wont run, the checking breakers/fuses etc is a waste of time, as the transformers clearly providing the 24 volts to operate the contactor outside.If you switch your fan to "on" does the fan run?if not, check fan relay, or board or motor/cap etc.If the fan does run with the fan switch set to on, but not in cool mode, the auto function that sends power to green /fan via yellow?cool terminal in the tstat is open and not allowing the 24v to energize the fan relay.

You need to determine if you are getting a mains feed to the fan motor, if not, then you need to trace the wires bcck to source and work from there,
If you are getting a 240 volt supply, then the new fan is faulty.
Hope this helps you.

either the fan is bad or you need a temp. sensor, to check fans, run a wire from positive on fan wires to positive on battery, if need be ground fans!! if they are ok the fan should start running,,
