Hello , this is Bobby and I have a Coleman Mach rooftop air conditioning unit Model # 8335B8964 when I turn on the unit ,it throws the circuit breaker . I have replaced the starting capacitor and the running capacitor for the compressor, the fan runs ok.Is there a circuit board for this particular unit?

Here's a link to a service manual, with step by step tests to determine whats wrong. I'm thinking compressor shot, but this should confirm, and or help you determine for yourself. Be careful with those capacitors eh !! Read warning in service manual.

my heat and air conditioning wont blow out through the vents

Check the air handler to see if the blower is on. First check the circuit breaker which gives power to the blower.

If the condenser outside is not on, there is no power anywhere. Again, check the circuit breaker.

Also possible faulty thermostat.

air from a/c does not cool; compressor does not turn on

1: Pull out the "Service Breaker" located on the Wall next to the outside unit.

2: There are 3 Wires running to the Compressor.

3: Check to see if any are "Heat Burned" and replace.

4: Put Service Breaker back in from step #1 and try unit.

If that doesn't work call me.
No charge for any further advice
