How do I replace the high-pressure cutout switch on my Ruud heat

I have a Ruud heat pump, and the high-pressure switch has gone permanently open-circuit; I have it bypassed and the unit is working fine for now.
The pressure switch has a copper capillary tube which is soldered into a filter housing or something, which is a permanent part of the main refrigerant line; the other end of this capillary is attached to the pressure switch with what looks like a compression fitting. If I unscrew this fitting, will all the coolant leak out?
(i.e., will I have to hire an A/C mechanic to replace the switch for me?)

Since you have switch by passed make sure the condenser is clean. you run the possibility of trashing the compressor. "burning it out" the high pressure switch is a very good safety I recommend a certified contractor to replace the switch and give the unit a tune up for best performance cleaning both coil then checking the charge.

Our Ruud achiever heat pump's ac will not kick on?

Hi, there is no reset button for your high pressure switch. You need to see if you have lost power to the unit. Check the circuit breaker. By the unit, you will have a electrical box, disconnect. Raise the cover and pull the plug. You should have 2- fuses there, most do. If you can't see any go one step further by removing the plastic cover and see if they are in there. If so, try replacing both fuses. This is where you need to start. You will have high voltage to the unit such as 208/230 and control voltage from the stat and indoor unit of 24 volts. Find out and make sure you have high voltage first and let me know. Use my user name below, and get back to me, we may have to go into it more.

What if your unit is not turning on....but the inside unit is still heating..

Most heat pump systems utilize electric strip heaters as back-up and emergency heat. This will allow the system to continue to produce heat in the event of heat pump failure. If you are having problems getting your heat pump to turn on, you might have a blown line voltage fuse, a tripped circuit breaker, or a high pressure switch tripped. The high pressure switch on a Rheem or Ruud unit is a red button located near the service valves at the outdoor unit. Try pushing the button to reset. Check your indoor air filter and replace as necessary.
I hope you find this helpful. If you continue to experience problems, please let us know and we will dig deeper to help you. :-)

I have to reset the pressure switch continously when I turn on the heat. The temp never reaches what is set on the themostat.

I take it that this is a heat pump. Check your coils and your filter, make sure they are clean. It could be a dirty eveperater coild or dirty filter. It could also be a freon issue (to much freon). Heat pumps are touchy when it comes to Freon pressure. When in cooling mode, it's not that cretical but when in the heat mode, it has to be real close or you will have problems. Normally, the pressure switch is set off due to one of two reasons.
  1. The unit can't get rid of the heat causing the pressure to build to high.
  2. To much Freon pressure.
Good luck!

High pressure cut out control module is locking out the restart of condensor, if you hit reset button, condensor will start up, changed air filter.system is a ruud 12 seer heat pump with scroll inside

You need to pull the condenser shroud and hose down the outside unit really, really well and I can't stress that enough. The pressure switch helps protect the outdoor unit. There are only two things that will cause this to trip.....dirty condenser coils and a blockage in the high side of the unit. On a Ruud, to clean it good, you have to remove the shroud.

Ruud 12 seer heat pump not heating

It sounds like the unit is tripping off from high pressure. Check you filter and indoor coil. You may have low air flow inside that is causing the refrigerant pressure to be to high.

Ruud heat pump high pressure cut off problem

That's going to be in your installer configuration. Check and make sure the G terminal has a wire connected to it at the tstat , and that connection it tight. In the configuration menu, make sure it is set for a heat pump, elected heat. It seems to me that the tstat doesn't know its connected to a heat pump. Should be able to locate aodel # for tstat on the back of it. And ask Mr. Google for a manual, if you don't have 1. Hope this helps!

Newer High efficiency A/C's are not compatible with the older systems for many reasons. They use a different refrigerant, have a different oil in the system for lubrication and they operate at higher pressures than the older systems using refrigerant 22 which is being phased out. It is standard procedure to replace the entire system when upgrading.

RUUD Central Air/Heat Pump

Start with the simplest first it,s not fun but it's necessary EVERY TIME. Clean your evaporator and condenser coil, change your air filter. Getting to the evap. coil is often a real headache and a result doesn't get done often. When its clogged as you probably know the refrigerant can't absorb heat at the coil so it tries to absorb heat on the way to the compressor freezing the hot gas line the safety circuits that protect the heat pump compressor from getting liquid refrigerant back to the compressor almost immediately will take the compressor of line (looking somewhat like a defrost cycle). I hope this helps it's a tough repair GL!
