TempStar DC90 Starts/Stops/starts

[mosleyh]

I just bought a house that has a TempStar DC90 as the main floor A/C unit. The thermostat is a Hunter 44668. When the A/C cycles on, I hear the relay click in the thermostat, and the A/C comes on normally. 30 to 60 seconds later, the A/C goes off for a second or less, then immediately comes back on. I DO NOT hear the relay in the thermostat kicking on or off when this happens. It only seems to happen one time after the thermostat turns the unit on. After the one extra off/on it runs normally until it gets to the set temperature.

 

Any idea what's going on?

 

Thanks

Can you locate the m/n

or post the schematic?

Sounds like a blower issue.
