Start with the fan motor capacitor, check it . usually 5, 7.5 or 10 microfareds.check it with a meter on the uf scale, or label wires pull it and take to electric motor shop and they can check it. if cap is good then trace wires from motor to sources of power and see if you have 230 volts to motor . if you do then motors shot. label all wires and note exactly where the fan blade is located in relation to the grill guard. sand motor shaft smooth. oil loosen bolts on blade hub and gently remove. take old motor to motor shop and buy exact replacement motor. or have motor shop man show you where to place wires. usually black and white to power, brown and brown with white stripe to the capacitor. some motors wired up with three wires. see side of motor or directions in box or ask motor man to explain. resecure new motor exactly as removed , reinstall hub and blade. if you think blade is to rusted to get off or you mess it up just take it to the motor shop. he sells blades to! just be sure you have good clearance when you get done, cap off or tape off any unused leads. i usually use little bits if stat wire to secure wires up and out of the way of the fan blade if needed. they last longer than plasties and are not effected by the sun etc. check rotation of blade. cupped or curved side into the wind . check amps on new motor. should pull less than rated . a 2.9 may pull 2.1 etc. a new motor always deserves and usually uses a different size capacitor than an old one. they are cheap anyway and not worth skipping and having a redo. good luck........

I have a Dometic B3200 / 3253.332 roof a/c The problem I have is on a very hot day the a/c will run for lhours at a time then the fan will cut out however you can still hear the compressor

it is possible that the condenser is too hot to transfer the heat because the air temp is too hot
test that by spraying water into the fan ( mist) to cool the condenser and see if that stops it
or move the unit to a shady area rather than on the roof top

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.

The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Is the heat pump cooling itself down? It is a combination heat pump/air conditioner wall unit.

If a unit is in heating mode the outdoor unit is in cooling mode (outside always does opposite of indoor) after a while if there is a build up of ice on outdoor coil unit stops and puts hot gas through outdoor coil to clear it. The indoor fan stops to avoid and heat loss in area served buy unit once this has been done and indoor unit coil is hot again fan will start. This is the correct operation of the unit to save against bust could and reduced efficiency

Neff fridge/freezer has stopped cooling

pull the unit from the wall, remove the bottom back panel , see if the small fan is working ,if the fan is , there's probally alot of dust back there,unplug the fridg. and vacuum the area real good,use a flash light to make sure you get it all, if the fan is not working and the compressor is running the fan is the problem ,the fan keeps the compressor and coils cool so the freon can cool down so the unit works like it should,if the freon is hot ,the air the fridg.will be blowing will be hot. this should fix your problem, and YES its worth fixing.alittle p.m.saves alot of $$$$$$$$$

Both radiator fans have stopped working. Not the fuse.

have you tried to hot wire them to see if they work? If they do it's probably the sendor unit on the engine or radiator not giving the signal
