3 amp fuse blows when call for gas after pilot runs for 30 seconds


check the blower motor for seized of burnt out. Fuses blow because of excess current draw and in this case if the fan is not starting everything will stop. The gas will be set so that if the fan is not running the gas will not be allowed to turn on

When furnace runs blower won't run.as soon as furnace stops blower runs. They never both run.


Sounds like fan limit switch/fan timer

This will cause the main burner to run untill the over tempreture switch is tripped therefore shuting gas supply and running fan on high till over heat condition is resolved then it will restart burner and repeat
continuing to run heater like this will cause heat exchanger split.

first have the heat exchanger inspected for a hole or crack, if there is an oval to round adpt. on top of unit or an elbow in vent this can cause the heat exchanger to split open and also cause what you are talking about.

HAD Carrier Digital unit, did not like, purchased Hunter, which I could not get to work Now I have extra colored wires hanging from the wall that came off the carrier that I did not tag.


Put the carrier unit back on the wall and connect the colored wires to the designated terminals.
R-Red, G-green(fan), Y- yellow and so on until they are all reconnected.
Manufacturers controls are designed to operate their units and sometime have more control options that require the extra wire you experienced with the off brand unit you purchased. Take it back and get the instruction manual out for the Carrier unit and learn to like it. If you have aZone System it is the only cotrol that will work with your system.

Air con runs for 5 mins then stops, unit outside still going


ok depending on what part of the world your in and the season . Winter: most split systems are designed around a set given temperature of operation , if this is a heating problem the what you are experiencing is the system going into deforest . bare in mind that those carrier splits are manufactured in china and are designed for about 35 deg C in summer and +5 in winter , anything out of this temp range will cause this , especially if it is running on freon 22 , in-which case it sounds like its short of gas to me . if its a new R410 a system , then check your filters and if they are clean and its still doing the same then it too is short , in each case a refrigeration mechanic is required.

York Mini-Split Not Cooling? : (


This can only be a gas problem.
the split units goes on on and off if a shortage of gas is involved, the chances that you would here it wont be that big for the fans would make too much noise.
get a repair man for a re gas and all is well.

Good luck.

Carrier air conditioning unit #38ckc042


Yes, the wires for your thermostat are low voltage 24volts, and there is a fuse that protects it, now if the fuse is gone, nothing will work until you separate the wires and put a new fuse, the fuse is inside the ac unit, if you cant find it, that means it doesnt have one. there for need to check voltage at the transformer.
