I have a Enertech unit Compass Series by Geo Comfort It Was installed about 5 years ago and been running very good . Last night red light came on the thermostat and it switched to electric heat. Opened panel on the unit and found out that low presser switch light is on. Checked filter and it is clean and no obstruction on air flow.In the troubleshooting section says that we can try to jumper LP switch and see if its faulty switch.How can I tell whether it is faulty switch or real fault.

You could jump the 2 wires on the switch and see if the unit starts up.....Don't run it too long without the low pressure protection....

Finaly fixed!   TX valve had to be replaced. Seems to work fine , no more faults but compressor is freezing. Serviceman came back and tested the system but couldn't find anything wrong. Specialist from  the Company will be troubleshuting the system this Friday and hopefuly fix the freezing problem.
