The inside sytem fan is running but the compressor outside only kicks in for a second and then stops even though the room is not cool. The inside unit fan will run for a few minutes after that and them the timer light will flash up on the unit and it cuts out. I have cleaned the filter inside and the condensor outside so nothing is blocking its air flow. It ran fine for a few days in the extreme heat but now isnt happy.

Re: Sharp split system, cutting out
If this is running in A/C mode, then I bet you have a low refrigerant charge. The compressor is dropping out on low suction pressure if it's cutting in and out every 5-10 minutes or so. If it takes hours, then it's likely a different problem.

This sounds like a split system, the condensing unit outside and the evaporator coil and fan inside. You must be referring to the indoor fan, since the compressor and outdoor fan are controlled by the same contacter. The indoor fan relay contacts sounds to be welded shut, and needs to be replaced.
you can check your heat pump on the outside by turning off the power and listening to see if it makes a whoosh sound. and then turn it back on you should hear it kick in. Is the outside unit running? Sounds like an electrical problem maybe in the breaker or the contactor on the inside of the unit. This is where the 24 volts from the thermostat call to the 240 volts to kick on the condenser fan and compressor. Be real careful in messing with this because of the high voltage.
You amy ahave a bvad capacitor on the outside unit. It starts the fan and the compressor. You can change this yourself. Open the outside panel and you will see a silver canister with terminals out the top. Replace this and I think your problem will go away. On the cap. it will say something like 30uf 5uf 370 ot 440 Just get these numbers and get a new one. Russ
be aware that not repairing this asap that you are causing yourself more problems First I would change out the fan capacitor and see if this could be the problem. Secondly if the capacitor isn,t the problem change out the motor . By continuing to allow the system to cycle like this the compressor will take a dive on you costing more . Good Luck
Check your wall thermostat to make sure the "fan" switch is in the "auto" position. If it is set at the "on" position, the indoor fan WILL run continuously. Not really enough info as to what type of split system you have. Gas? Electric? Heat pump? Oil? Wood? Newspapers? See what I mean? Is it variable speed? Do you have a "special" thermostat for certain operations? Does your system incorperate inverter technology?
If the inside unit (evaporator) is turned off absolutely.
The condensing unit must be turn off outside because the power
are derived comes from the evaporator.
Possible it seems on the cut out stage inside and remain the power still on
Otherwise theres somebody tamper the connection?
Fan cable consist of 3 wires
1 Common line
2 Start /stop line***Change the connection of this wire where it located, To On/ Off switch of the
evaporator inside unit
3 Ground green line/Earth
note: you can get all that wires inside the power supply in evaporator area.
This question is really to broad to answer. There are several things that could cause it to stop running. I think I would turn everything off, let it cool down for several hours and try it again. When you kick it back on, take note of what is running and what's not running. Inside fan, outside fan, compressor. If the outside unit will not run at all it could be as simple as a grasshopper caught in the contacts. If you hear the compressor running outside but no outside fan, The fan motor probably needs replaced. Please make sure that all power to the unit is TURNED OFF before removing cover plates on outside unit and before trying to remove insects from contact points. Check all wiring inside outside unit while it is open. Also check capacitors for swelling or leaking. If you don't know how to turn all the power off or open the outside unit, you need to call a professional AC technician. Hope this helps.
