Question about Samsung Heating & Cooling

1 Answer

Dear Expert, I am the owner of a split type room air conditioner (cool and heat) SH24TB5. During cool mode it works very normally. During heat mode is the problem. It starts the heat operation normally only for about 1 minute. Then the outdoor unit suddenly stops following by a loud noise. After 5 minutes it restarts and it does exactly the same as before. Please give me your assistance. Thanks in advance. Yannis

Hi,
Most likely you have a stuck check valve....
When the reversing valve switches for heating, the check is not opening so the pressure builds till the high limit shuts it down and then the compressor shuts down...
The pressure then spins the compressor backwards which makes alot of noise...

Find a certified refrigerant tech. that can diagnose the system and change out the bad valve...
This is NOT a DIY project!!

What is the difference between a ducted and non ducted Domestic Air Conditioner?


Ducted A/C has an internal fancoil unit installed in the roof space of the home. From this central location, a series of ducts run from it and into as many rooms in the house as the owner desires. From these ducts, this allows you to cool or heat each room individually – called zoning
Split systems stand out for their relatively low initial purchase price. Another perk is that the installation is not so invasive – it can often be done in a day or less from a licensed technician. Though, being that the unit is fairly small, it is best suited to cooling or heating one room – this is either a positive or negative depending on how you look at it. On one hand, it’s an efficient option if you only need to cool or heat one room, but on the other hand they are less effective in larger spaces. Rarely could a split system air conditioner cool or heat an entire home. Split system air cons are great options for small areas, but lack the power to affect larger spaces – this is reflected in their relatively cheap purchase price, from around $1,000-$2,000.

Teco Split air on will not heat the room


Are you sure it's a heat pump type? If so, there is a valve in the outside unit that may be stuck or not getting power from the pcb. Give it a tap and see if it changes over

The heat sistem is not working well is working but 30% of eficency than it was working beafore.It hear like water on it ..help im frezzing


Air conditioning real definition is not giving cool but removing heat from the room. In same way for heating, it's not heating, removing cool from the room. When your indoor coil, air filter and blower wheel are full of dust, you won't get even 30% of cool or heat depend on your selection.
Simple solution for your problem is clean indoor unit completely. Check all sensor is working well. In heat mode keep temp minimum +3 degree than room temp. thanks and helpful.

Keep heat mode and temp setting+5 degree than your room temp.Still no heat check power to heating element. No power replace heating temp senor. If it's with RV, check power to RV and also warm in suction pipe(higher size pipeline near compressor).

Soleus KFGHP-09-ID Mini Split


This is normal operation for these styles of minisplits. The thermostat is not in the remote but is located on the return air of the indoor coil, so the air needs to be flowing in order for the thermostat to measure the rooms temperature. Set your fan speed to auto and the fan will slow down when setpoint tempurature is met.
