Why phase reverse switch only works when cold?

On my Spectral DMC20 phase switch only works when unit cold. In recent heat wave (104-113 degrees) I turned off electronics fearing ac failures. When I turned on today discovered phase reverse works when the unit is cold. After warm up switching again gave silent in reverse position?

Bypass the phase switch all together and use the cables to swap phase. No cost fix ay? Never have a phase switch problem again either.. 

The better way is to have a "POT" 0 to 180 degrees out of phase.
