Hello everyone. I've got a problem with a multi split I installed in July.
UE: RAS-M18GAV-E
IU: 2X RAS-M10SKV-E
The call came last Friday that one of the units just kept blasting out heat non stop.
The other unit cycled properly whether it was working on it's own or in conjunction with the faulty unit.
As the faulty unit's connections went straight out the wall behind it I decided to make sure it wasn't just drawing air from outside over a temp probe.
After plugging the hole with silicon I switched the unit back on and after a few minutes I increased the temperature demanded. Off it went ,working away nicely and after a few minutes I reduced the temp setting to 21°C and as would be expected It slowed right up.
This morning the costumer called to say he had switched it to auto mode and the unit went into cooling and once again didn't stop even when the room got cold. He had not changed the temp setting.
I'm wondering if the problem is a faulty return air temp probe.
Could that cause this sort of problem?
BTW only the green operation light is on and not flashing. And I remember seeing the orange pre def on the other day but once again not flashing.
Has anyone else experienced this sort of problem?
Thanks for any replies.
