SOURCE: Need an expert on Grunaire Mini-split systems.

If you are low on refrigerant, and if you have a low pressure switch, it will not allow the compressor to come on in heat or cool, until you put a jumper across the low pressure switch or add enough refrigerant to get the pressure up to close the switch. You can only add refrigerant to a system if the bottle pressure is higher than the unit pressure without the compressor running.
Normally a technician will hook his gages up if suspects the unit is low on charge or he will push the contacts closed on the contactor and feel the suction line to see if it's cold.

Good Morning Friend,

I understand that you are receiving multiple error codes on your Frigidaire Affinity washer, model# FAHE4044MW. I see that the error codes showing are "E", "PA", "AU", "U5", and "5E". I suggest resetting your washer, by either unplugging it or shutting the power off at your homes circuit breaker, for 3-5 minutes. When you restore power, start any cycle on your washer. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your washer status has changed successfully. Hope this is helpful.

I also have a grunaire dual zone mini-split that doesn't work worth a ****. I've had it looked at multiple times and had freon r410a added twice and still nothing. Without the high side - how do you know...


an FC fault on a Grunaire is typically a defective PFC board in the outdoor unit or a Grossly overcharged system, where the drive cannot overcome the standing pressure to start the system up...

the ONLY CORRECT way to charge one of these units is to WEIGH in the charge..

the Label on the side of the unit will give you the correct charge amount.. this is for 25 feet of Lineset on Each indoor unit... typically on a 9 or 12k btu indoor unit (1/4" liquid line) you will add 0.7 oz refrigerant extra per extra foot of lineset.....

the PFC board failure is a very common failure on all of the grunaire / chigo built units...

Compressor shutting down


FC IS FREON CHARGE, WHAT YOU ARE GETTING IS A HIGH PRESURE CUT OFF  FAILURE. THE LABEL PRESURE IS TEST PRESURE. THE RUN PRESURE ON LOW SIDE IN AC MODE IS ABOUT 65 AT 75 T0 80 DEGREES INSIDE AND ABOUT 200-300 HIGH SIDE AT 75 -85 OUTSIDE TEMP. IN HEAT THE LARGE COPPER LINE BECOMES HIGH SIDE HOT WHEN YOU FEEL IT. IF YOUR FREON IS LOW WILL WILL ALSO GET SHUTDOWN. YOU WILL NEED SET OF FREON GAGES AND CONTACT ME BACK
