It sounds like your heater is shutting off because the ambient temperature is higher than or equal to the target temperature you've chosen (shown on the LED display on the front of the machine):
The heater's intelligent thermostat is engineered to turn the machine on only when needed when the ambient room temperature drops below the target temperature. However, we're happy to help you make sure your heater is working as intended. Please give us a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

compressors dont go weak either valves are failing -or unit motor failing --and if have leak will need fixing and depending on where and why leaking not cheap --get 2nd opinion
If you increase the airflow, the blower moves more air across a cold coil and less moisture is removed due to less "air to coil" contact. If the air flow is slowed, the air passing through the coil is at a slower rate giving the coil more contact time and removing more moisture. Faster speeds for more area coverage. Slower speeds for lower humidity. In your instance, if you have a cold set temp(72°f or lower) your unit will run a lot no matter what speed the blower is in. But, high speed less moisture removal. Unless set temp is set too low. And if I can ask, why is too much moisture removal an issue?
The E-4 message indicates low on refrigerant (R-410A type) You will need guage hose adapters sold by Ritchie/Yellow Jacket # 19173

it is likely low on coolant or as some say "freon" that or the indoor fan motor has not run properly. let it thaw completely by shutting it off and just turning on your fan switch from auto to the on positon. if you begin to feel air flow eventually you need coolant added b/c you probably have a leak from the system being old
I am experiencing a similar problem with my Mitsubishi slimline MSH09TW unit; about 4 years old; It use to give us very hot air now it is giving some what hot air; northeastern USA current temperature about 15F. You think frigid weather in Cranbury NJ could be responsible or some thing else is going on. Please help me if you have some time and knowledge about Mitsubishi heat pumps.
Sincerely,
DSS
