There could be a lot of reason but most common reason for unit tripping breaker is bad compressor .
Disconnect compressor and turn breaker back on and if breaker didn't tripped then it's definitely the compressor. If breaker still tripped then there are other issues .Check all electrical wiring because something is grounded

you need to get in a technician to find the reason for the breaker tripping
it could be problem insulation or pest infestation causing ground leakage
otherwise you will be wasting money on the repair by replacement merry go round

There are many reasons why the 'inside' fan motor could not be running, however, the obvious one is that the breaker (to the inside unit) has tripped, and needs to be reset.
Hopefully, that might be your only problem. Sometimes they (breakers) will 'trip' for no reason, although most of the time a 'tripped breaker' is an indication of another problem.
If resetting your breaker does not cause the motor to run - then your best solution would be to have a AC Tech troubleshoot it to find out the cause.
Hope this has helped.

Circuit breakers for water heaters generally operate at their maximum current. Once in a while a circuit breaker will trip for no apparent reason. The other reason may be a fault with the element or the thermostat. If this is the case it will generally happen again. If it does the element and thermostat need to be tested. If there is a fault the c/b on the HWS should always trip before the one at the switchboard providing that they are the same rating.

Check mains supply it may be low coursing Cuicit brown outs

Could be a lot of things - but I'm wondering if when you are checking the 'fuse at the plug-in,' are you actually checking the outlet for voltage?

I would check the outlet for voltage; i.e. plug in a hair dryer or something to the outlet and see if it (hair dryer) comes on. If it doesn't then I would check your breakers and see if you have a breaker tripped. In homes - you can usually go to your breaker panel (usually in the garage or a store room, i.e. pantry, hot water closet, sometimes in hallways behind doors) and find the breaker panel.

On a small unit like yours it would probably be a 15 or 20 amp single throw (like a light switch) breaker. If it's 'tripped' it can be in a position that resembles half on and half off, or it can look completely 'off.'

Remember - if it's a 'tripped breaker' - just re-setting the breaker might not solve the problem. There is usually a reason for a breaker tripping - although they do on occasion 'trip' for no reason.

In any event - if it's a tripped breaker - i would reset it and then if it happened again, either within a few minutes/or an hour - or within a day or two - then I would suspect something wrong with the unit and I would need more information, or you might need a qualified technician to trouble shoot the unit.

Note: if the breaker is tripped and when you reset it - it immediately 'pops back off.' Leave it off and call a tech - because you have a direct short and it will have to be trouble shooted.

good luck!

two main reasons breaker trips is the pump motor jammed [not turning]or the heater shorted out --disconnect power open access panel disconnect the lines to the heater turn on power if breaker trips than motor /pump problem if doesnt trip than heater problem can order heater replacement online or pool spa store--if motor pump check pump for debris and motor for lube if u can turn shaft or impeller oil motor and work it into bearings if still not turning possible need to replace motor unit

Breaker is to small , if the full load amps of the unit is 95 amps , to correctly size the breaker to code multiply the full load amps by 175% minimum and 225% maximum. A 200 amp breaker is the size breaker that I would recomend for this application.
