Ambient around 30°F.
Suction 90 psig (R410A), evap below freezing.
Defrost is initiating but not clearing the coil before it drops back into heat.
Looks like either weak heat during defrost or defrost ending too early.

Anyone seeing more sensor placement or defrost timing issues lately in these temps?
