It is definitely with the compressor. It should more like you may have a weak winding in the compressor, you can a hard start capacitor (sp5 ) that will help the compressor on restart. Note that this is a last chance solution for a compressor.

SOURCE: ruud UAKB-018JAZ outside condensing unit will not run

Trace the wires (small cable) going to the out door unit. This is your 24v control circuit. when it enters the outdoor unit it ties to wires routing through the inside of the unit trace these down. For AC units 1 usually goes directly to the "contactor" (the item you push in and the unit runs?) the other wire can also go to the other side of this same item. But I suspect it goes through other tings before it finally gets there.
Some items are the high and low pressure switches and a delay timer.
A red button sticking out where you can reset it is the high pressure switch and if it clicks and lets it come on you may have a dirty outdoor coil or a fan motor outdoor that is not operating all time.
A low pressure switch has no reset normally on AC or HP.
A delay timer will have 2 3 or 4 wires depending on the type of timer. 1 of these wires goes to the contactor (usually) and one of them feed this wire. remove the wire going to the contactor. now 1 at a time take the other timer wires and touch them to the wire just removed. if the times is bad the contactor will click when you touch one of them with the removed wire.

If its a heat pump you will have to make the contactor try to come on around the board. and this you will need some knowledge on which and what feeds your contactor. Here Id suggest a technician. If I had a way to see your setup and wiring I could talk you through this but its too hard to type and would take way too long.

SOURCE: My Ruud outside condensing unit stops running when

Check condensor coil to see if it is dirty. It is kicking off on high head. Take a water hose and wash the coils this will help. Take the cover off and wash the coils by the compressor those get the dirtiest. TURN OFF POWER FIRST. Russ

SOURCE: I have a Ruud 10 Seers airconditioning unit. It

First thing is to check your air filter(s). Next make sure the fan is actually running. Also check the indoor coil and make sure it's not choked up with dust and lint. If the fan looks like it is running to slow then turn the power off and make sure it rotates freely by hand and look at the fan blades and see if they need cleaning. Also a weak capacitor will sometimes make a fan run slow. Let me know what you find and I can offer more suggestions.

Condencer runs for 20 sec then off keeps repeting after 2 or 3 min goodman central system


Seems like it trying to start and then cuts out , possibly on overload. Try the machine on fan blow only , that will check the indoor unit to see if that is working. Then try cool or heat function while listening to the machine starting. If you hear a loud humming just as the fan starts, and then it cuts out, It could be a compressor issue. Possibly the start capacitor has failed.

THE OUTSIDE FAN MOTOR MIGHT NOT BE WORKING CAUSING THE COMPRESSOR TO GET HOT AND TRIP THE INTERNAL OVERLOAD IN THE COMPRESSOR - IF THE UNIT IS LOW IN FREON SAME RESULTS - WHEN UNIT IS FIRST TURNED ON DOES IT BLOW COLD AIR OR DOES THE AIR NOR FEEL COOL - JUST COOL AIR COULD BE LOW FREON - COLD THEN WARMS UP IS FAN PROBLEM

Rheem split system condenser high pressure limit/safety needs resetting frequently before it reaches the set temp of 76 degrees faren. what's wrong and what do i need to check?


Is the outdoor fan running? The fan cools the coils and compressor, therefore keeping the high pressure low enough to run. Either the fan is not working or its not spinning fast enough. Check the capacitor, or just replace it.

Heatpump r-22 rudd system,unit runs starts out heating then compressor stops in middle of heating ,this unit has a out side air temp. sensor just wondering if possible bad board or not


If compressor stops in middle, check the following.
1.Thermostat setting must be minimum +3 degree than your room temp
2. Check it's in heat "mode"
3. Check indoor and outdoor coils are clean.
4. Check fan motor is working alright.
5. Outside sensor and room air sensor is placed correctly.
6. Gas pressure is o.k
7.Check compressor is overheated, even all the above is o.k.

RUUD AC cycles warm & cold 24/7


Hello Anna Sounds like the compressor is overheating and stoping on overload internally.Then it cools down restarts and runs into overload again.I would like to see the freon pressures when running.Could have a clog/restriction in piping.I dont like that you went thru a compressor already, the original installition is suspect.The original (1st) failure cause must be corrected.Check the TXV valve replace, filter/dryer look for a kinked pipe are ideas for overheating.Make sure condenser coil is free (ari flow)& clean also.

Champion VR7F will not restart without hitting reset switch.


Solved this problem. It required a new motor starter (or at least one component from the starter. The main power lead running to the thermal overload relay had oxidized and was conducting current poorly. Each time it would run ( I did this with the motor starter cover off) the lead going to the bottom side of the thermal overload would spark then glow red during the tank fill. I removed the bad section of wire, and installed a new thermal overload in the starter.

The inside RUUD AC unit has ice and no cold air is blown


it is likely low on coolant or as some say "freon" that or the indoor fan motor has not run properly. let it thaw completely by shutting it off and just turning on your fan switch from auto to the on positon. if you begin to feel air flow eventually you need coolant added b/c you probably have a leak from the system being old

Ruud Heat Pump blows room temp on Heat and AC setting


A "Heat-Pump" is also known as a reverse cycle air conditioner, this means on heat the outdoor unit acts like the indoor section and vice versa. So in all probability you need to have it leak checked and recharged.

Compressor will not start.


Usually short cycling means that High side pressure is getting to high (due to not working condenser fan, or dirty condenser coil), or low side pressure is getting too low (might have low level of freon or restriction in sealed system). low side would drop dramatically if indoor blower is not running, so if air is not circulating thru evaporator coil, coil will freeze up and low side would be much lower then normal. Here is video how I found issue with package AC not coming on. Thermostat call for cool, but condenser would not come on, indoor blower runs ok.

Ruud heat pump outside fan


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.
