Ruud heat pump outside fan

The outside unit is tripping the reset button.
Once the unit is reset the unit runs fine.
Could this be a outside fan issue?
Maybe a bad spot on the motor causing a heavy load on startup.
When the outside unit is tripped the inside unit continues to run with no heat and the backup heat does not start?

    I have the same problem, the reset button tripps during heavy cold snow below 20F and i have no idea where this button is, i have the cover off but cannot see a reset button anywhere. any help would be great, why does it always trip the reset during snow? i have 2" high snow feet on the unit so it never gets more than 50% blocked with snow. we have 35" on the ground and i always plow a trail around the unit so it can breeth. I sometimes does block the fan grille though. do they make a side vent for the exiting air?

You may be right in looking at the motor. It uses a different speed on heat than cool. The heat cycle uses low speed, usually red. Some manufactures use blue (medium). Cool uses black, high speed. If you are confident, switch the low speed wire with the high speed and see if this changes anything. If the fan motor isn't the problem, check the other setting (cool) if the overload trips, you may need to look into a new capacitor or compressor, if so, you can install a hard start kit. these are start boosters, and are inexpensice, sometimes they will give another year out of the comp. but I've put them on and they have lasted 5 years.

What type of run capacitor do I need for a Ruud AC model UPNJ-031JAZ (outside unit)


Looks like it should be a 35/3 370VAC. If it is not legible on the old capacitor read the data plate on the fan motor and compressor. These should say "uf" or "mfd" rating. Good Luck!!

Where is the reset button on my ruud acheiver 90 airconditioner?


Should be a small button on the outside unit close to where the tubing is welded on the unit. This is a high pressure switch that trips if the unit gets hot , so be sure and check the coil for dirt , etc. The fan pulls air through the coil. If the outside of the coil is dirty it will trip the high pressure switch. Look under the fins, you will see the outside of the coil.

I have a Rheem Heat Pump unit. This winter, the outside unit fan at times trips off, but the inside unit keeps running continuously. I woke up one morning & it was 62 in the house. The inside unit ran...


Dear Friend!

Due to very low ambient temp, the fan will not run. Once the pressure build up, it's automatically run for some time and again cut off. But if you keep Heat mode and still tem not raised in your room means the reversable valve not working and hence the compressor and out side fan also will not work. Keep "Heat" mode and temp setting +29 to get better heat. Hope is it helpful?

My outside fan will not run and the inside unit runs constantly. can't push the reset button on unit outside


Your out door unit fan motor not runs due to pressure not build up at Heat mode. If its cool mode only fan runs with compressor when thermostat calls for it.

Without having technical knowledge, don't press any reset button. Hope it's helpful?

Our air conditioner stopped cooling last night. The fan runs. My husband pushed the reset button on the outside unit but didn't know if he is supposed to keep it pushed in or just push it in quickly or...


If it is a split unit this is a unit with a furnace and air handler inside with the condensing unit outside. If your inside fan is running ck your outside fan and seeif it is running. If it is it is probably the wires to the capacitor or the capacitor its self. Some capacitors have 3 wires this is a dual capacitor with a 5uf for the outside fan and a 35up for the compressor. on some there are two seperate capacitors one 5 one 35 uf. also it could be the wirng to the capacitor they will be melted and chared. all of this is located in the outside unit where the elect wires go into the unit you can removethe shell but first disconect the power there should be a disconnect switch near the unit. if not trip the breaker. be carefull with the elect.

Ruud heat pump, acheiver, 14 years old. The heat seems to be on but the unit outside is frozen over and fan out there is not turning. The motor runs all the time. Is this okay?


In the heat mode the outside unit should have the fan running. In the defrost mode, the fan should not be running but in both cases, the compressor runs.

Ruud Achiever 10 heat pump - outside fan won't shut off


Definately get this checked out. Some thing has shorted just enough to let voltage "Feed back" and keep the fan running. Could be capacitor, wires rubbed through each other, etc. A reset is a safety that is used when there is an overcurrent or over pressure situation. No reset set for this situation.
There is always an outside chance that if you touch the unit while standing on wet ground, you may get shocked. I firmly believe that something is allowing power to the fan in a feedback condition so don't let this go as it may cause damage to other parts.

Good Luck and let me know how you make out on this.

Fan running constantly in the house


Check t-stat and make sure fan is set to "Auto", that might be why fan is running all the time, or it could be a fan relay that is stuck closed. It sounds like you A/C is over charged or you have a bad high pressure switch, this was a common problem with this manufacture especially in the heat mode.

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 outside unit trips circuit breaker


Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.
