I have a Maple Chase 9600 programmable thermostat.
The heater seems to work fine.
AC does not work at all.
Reset breakers. Battery OK.
I can hear the thermostat click but AC unit outside does not come on.

Help please

1st thing check breaker or power to the a/c unit,, when you put it on a/c is the inside (blower ) working in a/c mode, if so check wiring, low voltage to the contactor it should click in at the time you put stat on a/c,,
