Can you look on the front of the unit and give me the model so I can pull a manual.It will be something like RHSL HM3617JA or similar. Also model on outdoor.It will be something like RPKB037JAZ or similar.We will go from there

Also tell me if the flash code is at indoor or outdoor unit.

Expert:  airheatman replied 4 years ago.

Where are you getting flash code? At indoor unit? What is model of indoor unit

Expert:  airheatman replied 4 years ago.
If you are referring to a flash code on the defrost board in outdoor unit,Please verify that you are looking at LEDs right. There is no code for #1 Off and #2 flashing. We will go from here.

it said on chart on outside unit low pressure switch. that is what led code chart said.

Expert:  airheatman replied 4 years ago.

My chart shows Low pressure switch to be #1 ON and #2 Flashing. If it is a low pressure issue, this is going to be one of a few things. Dirty filter or indoor coil causing low air flow, system may be low on refrigerant, or you can have a restriction in the refrigerant circuit such as a stuck txv(metering device) or reversing valve.

Do you happen to have access to a set of gauges to connect to the unit? And if you turn power off to unit, then back on, will it start and run at all, for even a few seconds?

i tried turning off and on and it didn't do anything. i have no gauges. I thought i put new filter in a coupleof months ago. Had same issue in march. Expert like yourself said it was probably low refrigerant. So i called local HVAC and they came out and it was working when they got here and said it wasn't low on refrigerant. I'll just have to call them again.

Starting to rain hard here and don't want to get soaked. I'll just hope it cools off tonight and doesn't get to stuffy.

Expert:  airheatman replied 4 years ago.
I understand your frustration.I would turn the power off to both units. Make sure the filter is clean so air flow is not restricted.Then turn power and thermostat back on and see if unit will come on.If not, it will be necessary to connect a set of refrigerant gauges to the unit to check the charge and see what is going on.Low freon is a good possibility.
