Ruud 5-ton 10 SEER heat pump compressor turns off after 20 minut

My Cruud, I mean Ruud heat pump shuts off the compressor after 15 to 20 minutes in the heat mode. I have not tried it in A/C mode. The condensor and evaporator fan continue to run but the compressor stops. The contactor stays engaged and there is 240 volts at all 3 compressor connectors. Could I have a bad compressor, or maybe low Freon? any help would be appreciated.

You may have cottonwood on your compressor. Before you spend any money, do two things. Rinse off your compressor to clear any cottonwood, and check your filters, they may need to be replaced. Hope that helps!

First turn it to cool and see how cold the big cooper line is if it is not real cold you could be low on freon but if it is cold your compressor is bad

3 ton heat pump with piston in air handler. After unit shuts down it makes loud fluid flow noise for about 2 minutes


adding a tvx will not help. the sound you here is the pressure equalizing and that has got to happen for the compressor to start again the next time. A tvx will give you a higher efficiency because it can adjust to changing temperature conditions. Only way i know to quiet the noise is to try to insulate the lines better.

Compressor size


Square footage is how you determine what size of an AC you need, say two bedroom house with 1500 square feet would require a 3 ton unit but I would go to a 4 or 5 ton depending on brand and what you may do in the future, Like adding a bedroom or bathroom and how many people will be living in the house, a heat pump normally last longer the bigger it is and is more efficient than a smaller size. Just think like this, a 3 ton will run 30 minutes to an hour longer to cool the same space as a 5 ton so if the five ton does it 30 minutes faster it will not run as long. And when it has to pull down the temperature again it will do it much faster. So less run time means faster heat or cooling and less energy is used. I have found that the bigger units are made better and last longer as a general rule. And to understand the 3-ton and 5 ton let me say that it means how long it takes 3 tons of ice to bring the temperature down 10 degrees, the old BTU’s British thermal units. However the bigger the unit the more well built it is normally and the less maintenance required. 5 tons of ice would get it cooler faster. But one thing to keep in mind a heat pump is only good for 20 degrees temperature range, for instance if the high range is 80 then the low side would be 60 in order for it to be efficient so if you have it set in the house at 72 degrees on the high side and low side would be 52 degrees. But the larger the unit the less time it would take it to recover from the heat differential.

Does my 10-seer have a 10 year compressor warranty?


If you take all the numbers off the compressor and condesning unit and call an authorized RUUD parts dealer in your area, they should be able to verify your inquiry.

Unless there was a special circumstance, most compressor warranties are 5 years, unless the compressor was replaced during the 5 year period, in which case you should get 5 more years assuming the service was performed by an authorized service company.

It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.
