Depending on the brand of air conditioner, it is either the removal of the signal voltage to the valve, or the constant application of signal voltage to the valve. Most brands on the market are powering the reversing valve in the cooling mode. This would be easiest as you would have to make no changes if you wish, and only switch your thermostat to Emergency heat instead of heat, effectively not using the heat pump. On Rheems and Ruuds for example, the unit is in cooling mode unless the reversing valve has voltage applied to it. If you have a Rheem or Ruud, no change would be necessary except to change your thermostat to a correctly wired standard version rather than a heat pump specific version. Many electronic thermostats have this built in. Like above, you could also simply use Emergency heat instead of normal Heat switch at the thermostat. Either way, heatpump wiring can be tricky for even a good service tech if they aren't accustomed to working with heat pumps. So its best to have this done by a service company that works with heat pumps a bit.
the reversing valve is what actually changes the refrigeration cycle from heat to cool. the reversing valve receives its signal from the thermostat.
first you have to turn the valve and see if it was just in a wrong position
sounds like t stat is programmed wrong, reversing valve coil is bad or reversing valve is stuck.
If your EGR valve is vacuum operated, simply remove the vacuum hose from the valve.

Heat pumps have a reversing valve in the outside unit. You are hearing a balance of refrigerant pressures when the reversing is energized or de-energized.
Hi, Good question and the answer is ( YES! ) as long <<<< as you are not taking up any fancy ideas of using it as a heat pump. Wire it in and set the reversing valve to stay on cool cycle and never reverse to heat and viola. Some units use energized reversing valve during cool and some de-energized. Its easy to find out. Just try it. Hope this helps: Jimiwane

Hook up common and yellow from inside unit to condenser
A valve guide keeps the valve straight. Valve keepers keep the valve secured.
