I have a problem with the Sinclair ASH-18BIS2 air conditioner, the cooling mode starts without a problem practically 5-10 seconds after switching on, but after switching to heating the external unit does not start. I read on the forum that the current on the reversing valve coil should be in heating mode, unfortunately it does not appear on the wires going to the coil. I wonder if it could be the fault of one of the sensors. Please tell me where to look for the cause.
Best regards
