Not blowing cold air, what should i do ?

Sounds like wiring issue to me. I've delt with units like this and there is a wire lead for fan only and a separate one to run the fan when the unit is cooling or heating. I'm only speculating here but I would bet money that this was improperly installed.

Dont get discouraged though because it sounds like its working (for the most part) if you feel up to the task find the manual and check your connections. Otherwise hire a professional.

Sounds like one or more of ofvyour 3 defrost components have failed which are defrost heater , defrost thermostat, and defrost timer or board

Look for a swolen capacitor.
Always be safe. OUTSIDE CONDENSER BLUES

Have your a/c pressure tested, the clicking could be the a/c compr coming on and off due to low freon, it will do that so it don't damage your compr when there is none or low freon.

they are seperate concerns, The heat usaly does this when the fins on the waterpump is worn, And needs replaced, As you throttle vehical your forcing more rpm which in turns provides more circulation. As for the a/c, Sounds like your low on refridgerant

See if you can reposition the thermister on the facing of the evaporator coils. That could be it or the thermister might be bad. They don't use copper/mercury sensing bulbs these days. They use these cheap thermisters.

check the fan from the freezer side if its not running /possible frozen or jammed will cause the refridge side to be warm the fan blows the freezer air into the fridge side to cool their is also a damper or duct control which can build up if no blockage or debris test fan for power if power than test fan it self if not running than repair or replace as necessary

Sounds like the switch is wired wrong.
When you put the switch on fan only the compressor should not run at all, therefore their shouldn't be any cold air.
Check the switch to see if it's wired right.

Hi,I`ll try to help,look at the low side reading when ac is running(before it cycles off...cluck sound),is it down to 10? 0? below ?If so have the expansion valve replaced and your ready to go.If not,if you have a high side reading,is it above 275 or 300?If so the cooling fan or fans are not coming on,find out why,cooling fan relay?fuses? If the fan or fans are running,then you have a restriction in the high side,either the dryer,or the condenser are stopped up.I I can be of more help,let me [email protected]

Make sure your fans are running. It sounds like your fans are not working all the time. With the AC on the fans should run constantly. Check fan relays and fuses.
