low/high high/low

[bcullen]

Hi my Mr Slim control at fan low runs high and viceversa. If this simply means i use the switch as is with no problems then fine. But would it be more efficient or could there be a problem if i do this???
It is a large ducted air con model PUH-3~6YK Thanks for looking

Indoor fan Hi Low control via X1 and X2 relays, why low runs high?
Something wrong somewhere. This is not correct .. but nothing relate to performance (of cooling or heating) but malfunctioning.

Just a thought. What if low is working ok but high is not working properly How do i check?? How much of a blast should i get from the high fan. how do i fix

bryan whats the model no for ur mr slim, have u checked the resistance on the motor tappings-unplug the fan motor,start the unit in low fan to check which pin is powered,then change to hi fan to again check that the other pin has voltage yo ensure the relays are switching
