You will most likely end up having to replace the coil and maybe the ac depending on the refrigerant it uses. A hard lockout can occur because the low pressure switch senses a sudden drop in freon gas pressure. Therefore, a low pressure switch is vital for its effective operation to deter serious problems by opening its valve. You can avoid the low pressure switch from opening by checking the freon level and refilling it as necessary. Doing so … If the low pressure switch was defective, a pressure switch did not open status code would be flashing, so the answer is YES. We go to Step 2. 2 19 2.
