Outside unit does not have a filter. You can try to pull the disconnect on the outdoor unit. Reinsert after 10 seconds, see what happens.

If there is 3 indoor units from one condensing unit
(6 pipes at outdoor unit) this is classed as a multi unit

All units will run correctly as long as they all require same mode, cooling or heating, if one unit decides to heat it will shut down until master unit decides to heat then it will start, for each unit to individually heat and cool there would have to be 3 pipes to each indoor,

Often the fan will cycle on and off on the heat mode. A cold air prevention mode is often built into modern Ac units whereby the indoor fan wont turn on until the internal system pressure is up to a certain point and heat is available to pump into the room. If the system cant come up to pressure or temperature then possibly the system is low on gas. Place your hand on the large pipe leaving the outdoor unit, it should be HOT when the system is on heating mode and running. If not Hot, then it is low on gas.

thanks for rating Good luck

When setpoint is reach unit would shut off .
If you put the fan to the ON position it would run all the time and ac would cycle on and off depends on the temperature

If this is aheat pump or reverse cycle unit that amps in heating is to high. Should not go over nameplate amps in heat or cool. Sounds like maybe two things. Overcharge and stopped up coil on the inside air handler. The reason for the high amps is in heat the head pressure is higher than normal. So check the coil inside and have the charge checked because that compressor wont run long pulling that much amps over nameplate. Keep in touvh Rus.

You need to check if the heat strip is still good on it or that it is receiving power. If its getting power, then the strip is bad.
