I have a Ruud heat pump and AC, I have to keep hitting the reset button outside on the bottom of the unit. Also my ac works OK but my heat won't heat . Any ideas on these two problems?

If it is the high/low limit reset

It could be overcharged with refrigerant.
It could be undercharged.
The coil could be dirty causing high head pressure.
It could be a defective or out of range control.
There are many possibilitys if it is the head/low pressure control you are reseting.

Look on the inside of the access door on the outside unit and see if you can find the control on the wiring and what the description is.
