Check the thermostat set up ..some has to be switched either by set switch on back or through the initial set up program of gas furnances. It appears as though it is set on a short cycle by default. Follow the instructions to the T. Make sure you have the proper thermostat for your type unit. some are for gas, some are for heat pumps, some are for oil, others are switchable with settings.
