Hi

yes you can buy the same rating fuse. and much better to put a circuit breaker, and more safe trip off.

how to check out your refrigeration compressor;
Modern Compressors have two operations that have to work together just to run. More items must be considered for them to work and work efficiently in systems. The 2 areas that must work together are electrical and mechanical. Either your compressor is broken inside or the motor and or start components are not working properly.

Electrical
Ohm the compressor terminals to ground and across to each other.
1. If any read anything to ground the compressor is bad. If not go on to the next step.
2.Your readings between the compressor terminals should all be different and you should have 1 low 1 medium and 1 high resistance reading.
Add the low and mid reading together and the sum should be close to the highest reading. If it reads say 20% more or less then retest it a couple of times to confirm your not slipping on the terminals. If you get only 2 readings don’t panic wait 24 hours for the motor to cool off for sure and recheck it. If still no reading then your compressor motor is open. A new compressor or replacement of the appliance is required. If you now get the 3 readings described make a diagram you feel comfortable with as to where the wires go to each component before removing anything, then continue:
3 Assuming the above checks out: Get a new *Start relay *start capacitor if so equipped relay *external overload and *run capacitor if it has one. In other words everything that is external and attached to the wires or terminals on the compressor or wiring per your diagram and replace them on to the compressor. Then if it starts problem solved if it still does same thing the compressor is bad (broken mechanically inside the compressor) and you have to decide to replace compressor or replace the refrigerating compressor be it AC or Refrigeration.

*May or May NOT have this component:
*Start Relay:
MOST 99.999…% of refrigerators of the household type have a start relay of some kind and they vary in size shape and color. It plugs directly onto the compressor. SOME AC units but not all have one and it is different. These Resemble a box about 2”X2” X 3” with at least 3 terminals on it and these 3 terminals are marked 1, 2, & 5. Each of these will have at least 1 wire on them and there may be other terminals (4 & 6) as well that can be used with several wires on each.
* Start Capacitor
100% of AC and Commercial compressors that use a start relay (and remember some do not have one but those that do…) and only some domestic refrigerators use a Start Capacitor. At least 2 wires going to a black (usually) cylinder which is the start capacitor. Start Capacitors ALWAYS HAVE 2 or more Wires and ALWAYS HAVE TO HAVE A START RELAY.
*External Overload
MOST 99.9% of Household refrigerators, 80%+ of smaller commercial refrigerators, and most 90% of window unit AC’s but almost no central AC compressors Have an external overload. Those that do not have an internal overload. These vary in size and color and description a basic one is round 2 wires and generally black about quarter size USA AND IF USED ALWAYS MOUNTED ON THE COMPRESSOR with the other wires and terminals there.
*Run Capacitor
Some domestic refrigerators (can be a small rectangular box) medium and larger refrigeration and (99.999%... of all) AC central and Window units have a compressor that requires a run capacitor. These type units also have a fan motor that can require a run capacitor. These Capacitors always have at least 2 wires and often 3 or more if the capacitor also is wired to the fan motor.
.
If a compressor is tight due to linear expansion from heat a tip worth remembering is as something cools it contracts, except for water at freezing. A few times I have gotten a compressor to start after leaving it off for 6 to 12 hours then retrying it. See the compressor unless left off for 6 to 12 hours and sometimes as long as 24 hours may have expanded parts from heat. About 1/2 the time it is ok after new start components are installed with a start capacitor and relay. The other 1/2 the compressor will be ok for a day or 2 then stop again. A “hard spot” in the movement of the internal parts in the compressor, and stopping on this hard spot it can’t overcome the “tightness”.

If you follow most of these steps above you will arrive at a correct diagnosis well over 90% of the time ( allowing for what is unusual or for misunderstandings)

10 years of doing refrigeration and this has not changed..
Please rate me as high as you can and ask me to clarify anything you don’t understand.

What size capacitor in a Carrier Heat Pump 38yh036300


This is a three ton heatpump must likely it is a 35/5uf capacitor. But if you can read compressor tag it will tell you size it requires and also fan label will do some for it.you will need to ask for a dual capacitor from supply house make sure you pay close attention to hoe wires hook up so you can wire in new on before removing wires make sure you have high voltage turned off to unit.take pic with phone this will help when you rewire

I have a carrier air handler heatpump can I use a Rudd heatpump condensor


Yes if they match up correctly. I would stay away from Ruud though. Best off with Carrier or Trane in my opinion. Also, if your spending the money to replace the condenser, you should spend the extra bit and replace the air handler as well. New systems use a new refrigerant that is more cost effective and better for the environment.

Using cigarette lighter for air pump


It is very likely the cigar lighters circuits wiring sizes are not suitable for the amp draw of the compressor, i suggest you not use it as a power source. Buy clip leads and solder them on and use the battery as the power source. You can obtain the electrical clips from any hardware store.

My Carrier XQB 184 D just quit blowing out cold air. I couldn't hear the compressor working at all. Is this a problem that can be fixed without too much cost or should I just buy a new one and do you...


SOME OF THESE HAD A 5 YEAR WARRANTY ON THE COMPRESSOR. CHECK YOUR WARRANTY, THESE ARE ARE NOT WORTH FIXING. I WOULD LOOK FOR YOUR LOCAL SMALL AC REPAIR SHOP AND ASK HIM ABOUT REPAIR OR CAN YOU USE IT AS A TRADE IN , MAY GET YOU A 5$ OFF

My duted air conditioning started blowing hot air instead of cold and then stopped. blew a fuse and now will not work


Sounds as if the compressor has gone bad. The blowing of hot air and then the fuse blowing lets you know the compressor is pulling a lot of amps causing the fuse to blow and no cold air could mean the compressor is locked up and therefore you need a new compressor.

Goodman Air handler blowing fuse if switch outside unit not runni


Sounds like your compressor in your heat pump is siezed . You can try a "Hard Start" Capacitor...which basically gives your compressor a kickstart and works 95% of the time when compressors get older....It's hooked up in parallel with the existing Capacitor...if you're not familiar with Electrical etc I would call an expert and mention what I said . If this doesn't work you will likely need a new Compressor/Unit . You could also have a short to ground in the heat pump side....likely the compressor is the problem however the original Capacitor could also be the problem

Very hot outside. blower comes on but outside fan


Check the voltage source for the fan and compressor
Check the start capacitor for the compressor.If its over heating :bad compressor

I turned my CA on and it is blowing warm air


This happened to me also. Either the fan motor on the heat pump has died (what happened to me) or the relay for that fan has gone bad. Either way you will need an A/C tech to diagnose it with a multi-meter. FYI even with warranty (on the fan part) it cost me nearly $300 for 1hr labor to replace the fan. If you are out of warranty you might search local places for a new heatpump fan and either do it yourself (if qualified) or hire someone.

AC/Heatpump units cycle numerous times blowing ambient air.


If the compressor never kicks in, I would check the start capacitor, thermostat and the compressor windings. Most times the start capacitor is defective. Some window air conditioners the fan will run while the compressor stop through the thermostat switch. If the thermostat switch is bad every thing runs except the compressor. Let me know, Thanks, Sea Breeze
