I arrived to a diagnostic service call. Upon inspection, I concluded that thermostat would not send power to reversing valve this was due to thermostat losing its configuration. Was unable to configure it back to a HP. Replaced thermostat and cycled system. Contactor is pitted. Dual cap-34/5 rated 35/5. Refrigerant levels:89/211 14SC. 90F in the house, it will take awhile to bring temp down.
