I'm not sure exactly what unit you have and what controls you have installed on the unit. But....there usually is a flash code schematic on the unit. Usually on the inside of the blower compartment cover. This should tell you what is wrong with the unit. It could have a low voltage short somewhere and is loosing the call for cool. So the answer can be a possible yes to your question but without knowing the flash code, it's hard to tell from my point of view. You might end up calling a service professional out to check it.

SOURCE: System will not start up.
This is a signal fault between the indoor and outdoor first make sure the dip switches are set start with the unit closest to the condensor set as unit 1 then next unit as 2 and so on the dip switches are inside the indoor unit on the pc board if you check the manual it will tell you which swithes to set, if this wasnt done when the units where installed they would have never worked i would also check the signal wiring between the wallmount and the splitter box / bc box and make sure there isnt a loose connection when you have ruled this out id say more than likely it is a faulty indoor board on the wallmounted unt

These units have circuit boards inside that have lights on them. These lights come on and tell you what the problem is. I have had 4 units do the same thing that yours is doing. The result has been that the compressor has gone bad. You have to get access to the control board to see the lights. There will either be one inside the inside unit or one inside the outside unit depending on exact manufacturer date.
Good luck and hope this helps.

Hi, the control voltage to both indoor and outdoor will always be 24 volts AC. If this is a heat-pump unit, the high voltage to the indoor and outdoor will be the same, 208/ 230/ 240/ 277. If it is a split unit with a gas fired unit, the outdoor will be 208 or higher and the indoor will be 120volts AC. I'm sorry, you have the inducer motor, so it is gas! My mistake. Yes, always the gas furnace will be 120 volts AC and the remote condenser will always be 208 and higher. As far as replacing the inducer motor with a different kind, it will have to be the same voltage, 120, and amps, R.P.M's, 60hz, and made to pressurize and be able to vent Hot gases also. It must fit and operate like the old one. They should make a replacement universal motor to fit? Check with some of the wholesale houses on this and they can locate a motor to fit. Keep me updated on this please Don.
