My condensor fan motor has gone out. It is an Emerson 4259 model. I can not find another the exact same. Can I replace with anything? As long as the shaft is the same and diameter of motor is same?

Check out the link. replace by shape and contacts.

Hard to be exact here but sounds like low freon if all motors are running inside freezer and refrigerator.

Here are two images hope they help. Actual Emerson diagrams are not easy to find.

Did you replace the fan blade or the fan motor? If you replaced the fan blade, is it exactly the same blade as the old one? If it has more blades, or wider blades, or if the blades are at a different pitch than the original, it is capable of moving a greater amount of air, but the old fan motor is not big enough in Horsepower to do the extra work. Thus, you should change the blade again to one that is exactly the same as the old one. If it is a window unit, you could try running the fan on a lower speed and it might work.If you replaced the fan motor, you must check to make sure that the new motor is exactly the same as the old one. You also could have it wired wrong, so you must check that also.

Sounds like your fan has gone bad. That would cause no airflow, resulting in no heat transfer and overheating.

That means it would not cool properl;y and would overheat.

Check for voltage going to the fan motor. If you have voltage there, but no fan operation, replace the fan motor.

which fan shuts down? Outside condensor fan? Or blower inside? If its the outside condensor fan motor you probably have a bad run capacitor or a bad condensor fan motor

the new one needs its own capacitor 5 to 7.5 uf hook to the 2 brown wires

these heaters in the wall come on when the house is hot to protect the fridge .there is a energy switch in the fridge that says ( if moisture appears) shut this off

I had the same problem with my 2630. Unplugged the power cord and pulled the small panel off on the rear of the unit. The fan was working. I noticed a lot of dust built up on the condensor- the cooling fins were full of it. I took my small shop vac and cleaned off all that I could on the the surface of the condensor. Thought I'd try blowing it out in case I missed any in the inner part of the condensor. Reversed the hose on the shop vac so it would blow air and turned it on. Dust blew everywhere! Just vacuuming it out wasn't enough. No more problems with the heat- that seems to have cleaned it out so that the fan can now pull air across the condensor to properly cool it down. Hope this helps.

Check the connection of the electrical harness to the fan motor. If it is fully connected and the motor still does not run replace the fan motor. The fan MUST operate at the same time as the compressor to properly cool the system. Spin the fan blade by hand with he power off. If it turns with any resistance the bearings are dry and in most cases the motor is replaced.
