[QUOTE="Worsedog, post: 3899698, member: 13555"] Measure the voltage again. Unless that a/c is a serious antique it should use 220 to power the compressor and fan. Also have someone in the house turn the termostat on and off to the a/c posistion. Listen to see if the relay in the condenser unit is kicking on and off. It will be a very obvious "clunk". If there is a clunk check the contacts (with the circuit breaker off of course!!) of the relay for spiders or ants, they love to hide there. If there is no clunk then the low voltage approx 24vac that controls the relay is absent or the relay coil or thermostat contacts are bad. Hope this helps. [/QUOTE]
