    rheem heat pump troubleshooting

    I have a Rheem heat pump that is tripping on high limit sensor. When gauges are hooked up low side is steady at about 70psi while the high side starts at 100psi and continually increases to 400psi when the high limit trips. This process takes less than 5 min. This is in heat mode. In cooling mode the pressures equalize and stay constant around 95psi. Any ideas are welcome.

    too few posts for pro enrty. chances are its over charged. rheem, ruuds (cruds) are sensitive to charge in heating and always run very high head pressures!! heating and cooling. may also be restriction. but am willing to bet thats its over charged

    thanks for the replies. Not quite a diyer, I've been stuck in the com install side of the business for 12 years. I am trying to broaden the horizen by learning the service end of our business. Sounds like my problem would be an obstruction or could it be the reversing valve. this unit has been in service since 2005 with no issues so i am ruling out the overcharged theory.

    No, DIY help in this forum.


    As a homeowner you should check your filter, and then call a hvac contractor.

    How about sticking something in your profile, so we at least can tell.

    Nothing wrong with wanting to expand your knowledge.

    You should get one of the service techs to help you on this.
    Post your obsevations, and what it was.

    Like control boards don't see too much trouble with reversing valve but thats a good guess There would be other thing more likely to cause this problem
