    Dometic Penguin II Low Profile A/C Only Runs Fan In Low

    Replaced and old Penguin II with new one (old one was intermittently working, tried capacitor, fan motor, etc. and couldn't get it).

    Wired it up same exact way as old one - but it appears the fan is only running in Low mode. Even if I turn the A/C off and run the fan I notice no difference between Low and Medium and High.

    Any thoughts on what may be causing this?

    Thanks!

    I've never seen a unit with more than two fan speeds.

    Ok - well only the Low is working... and even the Low seems to be VERY low. Barely blows air out the unit. So even fan set on High - comes out Low.

    This A/C unit has three fan speeds… Red, yellow and black are the wires for the 3 speeds… I have this unit as my front A/C for Zone 2 and the CCC2 shows three speed selections

    I’d be rechecking the wire harness to the control module
