Not blowing cold air
Lennox system.
Put gauges on and not getting a reading on the low side. High side is 50psi.
Sub cooling at 2.
Is it possible for the unit to be low on Freon without freezing up?

What does zero low and 50 high tell you?

How did you get 2° SC at 50#'s operating pressure?

I’m sorry I meant to put 0 for the sub cooling.

Lennox heat pump(410a) not blowing cool air.
Compressor, fan and blower operating at normal amps. Return air is 78 supply air is 74. Pressures are reading 0/50 psi. No sub cooling. No ice on the coils. Leak detector is going off at the Evaporator coil.
My question is the unit contains low pressure switches so if the pressures are low then why it’s not cutting the compressor off.
Second question, the control board have the red and green light that lets you know how the unit is operating. According to the legend the unit is operating normal.

Time to get a tech out there to look at it!
