    You have two boards it could be, the fan cycle board or the main board. The contractors are on the board.

Amana ptac during heat mode will blow hot air , then blow cold , but will cycle back to heat eventually is this Normal?


if the fan switch is in the Run position and not the auto position you are getting cool are when the heat element is not on. this is kind of like a way to circulate the air. look for an auto setting it then should only come on when needed. Keep in mind it is normal for the fan to start blowing before the heating element is warmed up, this prevents it from over heating, or coming on when the fan is not working

I have a zoneaire sea ptac unit that wont produce heat on the high setting but will on the low setting... would this be a bad capacitor?


Pls note the heat temp that you kept must be 3 to 4 degrees C* between room temp and required temp.

And also number-wise keep down will be high cooling and keep up will be high heating.

Tnx

Fan will only blow on low when heat is on


your fan most likely is wired for low speed for heat which is common. this should be determined when furnace is set up properly. motors that aren't modulating motors and are multispeed motors typically have low medium and high taps that come off the motor and go to the corresponding relay on the board. low and medium speeds are used for heat and high and medium speeds are used for cooling. but only one speed for heat and one speed for cooling many times medium never gets used. im not familiar with klimaire is this a mini split system and not a regular air handler. cause speed control should be adjustable from the remote. if its a split but if not reaching desired speed due to a malfunction in the units could cause it to run low speed just to maintain the temperature exiting the indoor unit.

Fan will not run on high. Compressor runs fine but the fan will not run on high. Works fine on low and med.


It's the mode switch contactors for the high setting just overview the wiring of the high cool or high fan contactors if it's not there check all leads for the high fan or high cool circuitry.

A/C blows weak/low volume of air through vents


I f it is fan that has more then one speed if you run it all the time,it may
not be on high sample : low fan speed runs all the time
med fan speed for heat
high fan speed is usually for air conditioning so if everything is good then it maybe the relay.
