SOURCE: 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.

Have you checked the freon level in this unit? If you are low or there is a leak it could be the problem. Hope this helps.

Hi, the outdoor unit will start to freeze when it is cold outside, but also it should go into a defrost mode to melt this ice either by the defrost board or defrost thermostat. You will know as steam will rise like smoke and some folks think it is on fire. If it never goes into defrost, get back to us and we can go through some things to check. Merry Christmas,

SOURCE: My amana ac unit over heats the circuit breaker

What you described 'shouldn't' be happening - "if" the outside fuses and the inside breaker are sized correctly for your air conditioner.

I would make sure that the fuses in your outside disconnect were the proper size (for your AC), and that the inside breaker was of suffienct size to handle the air conditioner, and whatever else might be on the circuit.

Note: You would never want the 'outside fuse size' to be bigger than the inside breaker.

For example: 50 amp fuses in the outside disconnect and a 40 amp inside breaker is a no-no.

Often, for whatever reasons - someone will put larger fuses in the outside disconnect than what is called for.

When this happens the inside breaker is the only safety on the AC.

The problem is - for whatever reason - your inside breaker should not be tripping off.

It's likely that the AC may be on a inside breaker "that also has other things i.e. dryer, electric range or Refrigerator," and therefore any of these components 'including' the air conditioner could be causing the inside breaker to 'trip.'

One way to check this would be to 'un-plug' whatever else you had on the inside breaker - and then run your air conditioner and see if the breaker trips. Let's say you have the refrigerator and the air conditioner on the same inside breaker. You suspect the refrigerator is causing the inside breaker to trip - so you unplug it - and then turn on the air conditioner. "Now" it does not trip the inside breaker and assuming you have the proper fuses in the outside disconnect - you could safely say the air conditioner is ok - but - the refrigerator might be on the blink.

It's also possible that you just have too much on the inside breaker and you need to plug the refrigerator in to another outlet.

Still, if it was me - I think I would really think 'hard' about calling a Service Tech out - and let him/her diagnose the problem.

Hope this helps.

No heat but fan keeps running


If the air conditioner compressor runs all the time the main control board might be defective. The main control board provides the voltage to the fan motor and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem.

Mod# PTH093A35AC: Unit has quit running. Blower appears to be frozen up. Prior to non-functioning it was making a loud clicking sound while running in heat mode, almost like coils were freezing up....


yes the blower can be replaced / not all that difficult have a screw gun ready though...several screws to gain access.... the unit normally comes as a sealed system (meaning no actually service ports to add freon but can be ported and a tap added to check and add refrigerant to system... these heat pump systems are great when working correctly ,but when it does drop below 20-25 degrees outside they will start to freeze as the defrost cycles in them are normally not very long and the unit cant keep up so in return they will start to freeze up, however if the blower motor started to go out and unit was running it will freeze up on you.... hope this info helps out feel free to repost with anymore questions you may have.....

Inside fan turns on when outside unit is in defrost mode when heat is selected. This causes it to blow cold air for about 10 to 15 minutes prior to the outside fan starting.


The inside fan will run while the unit is in defrost. The electric heat strips should kick on to help prevent you from feeling this cold air. When the unit is in defrost it is essentially running in the A/C mode. You should make sure the electric heat elements are working then go from there.

Hello
You may try cleaning the evaporator filter,Also cleaning the outside coil or condensor,Simple green works good for cleaning coils and a garden hose.

Also cleaning the evaporator may help.
When unit is running properly the evaporator should feel cool and wet from top to bottom.
Last,the unit could be low on freon.

Energy Knight heat pump refuses to blow!


Does this problem happen when the temperature is below 30 degrees? When it gets about that cold outside, the air outside is too cold for the heat pump to "steal" heat from. On the thermostat you'll find a switch labeled aux or emergency heat. Turning this switch on will operate a traditional coil heater inside the system, providing you with heat. The only downfall to this is that it uses more energy to heat this way. Try turning the fan switch from "auto" to "on". If the fan comes on, then we can rule that out. If the aux heat switch is NOT on, set the thermostat such that the system will try to heat. If the outside unit is running, the problem is either it being too cold like I said earlier, or there's a problem with the heat pump's mechanical system that needs to be serviced by a professional. If the outside unit doesn't run but it should be, check it's breakers at the panel, the breaker inside the electrical box that feeds it, and look to see if there's a reset button on the unit itself. Finally, check the air handler (part of the system inside with the fan in it) to see if there's any circuit breakers or fuses on this unit. Make sure they're not tripped/blown. If none of this helps, you definitely want to get a pro to work on your system.

Its 15 degrees outside and my amana unit is off. every so often it kicks on by itself and runs for about 10 seconds then shuts off again. while it is running the control panel flashes FP, what is it trying...


I was wondering the same thing about our unit until I found the specs online and read that it has freeze protection. When the temp goes below 40 degrees, the fan comes on to prevent damage to the unit.
