Check the float switch.
Hello, the snowflake flashing is a (supposed to be) 5 minute delay to prevent short cycling of the compressor. This delay can sometimes get stuck thus requiring replacement. To test , remove top of thermostat to where you can identify wires and terminals. Have someone stand near the ac unit for this test, and then take a wire or paperclip and briefly touch Rc to Y. This should start the outdoor unit. R to G will start the indoor fan

Normally, you should have 5 color wires: W-White, Y-Yellow, G-Green, R-Red and C-Blue.
The Blue wire is a common from the transformer on older systems, which is probably hooked to RC terminal.
Try this: Remove the blue wire and jump the RC to RH with the red wire and you will be fine. Blue wire should not be needed with the new thermostat.
This should also be stated in the instruction manual.
Hope this helps.

Your snowflake should flash for about five minutes, that is the time delay built into the thermostat. It should stop after that and your system should begin to function.

The 2nd combination is correct (w/ jumper). Wire nut or tape the blue wire. The snow flake shows it's going into cooling mode after a 5 min delay. If the AC is not coming on then the problem may not be the thermostat. If you don't have 24VAC between the red wire and the blue one the problem is at the furnace or it's supply. If you do, then check for 24VAC between the blue wire and Y on the thermostat(after the 5min delay) - if it's there the thermostat is calling for cooling. To check the heat, switch the thermostat to heat mode and use the W(instead of Y) on the thermostat(after the flame stops flashing).

That is a Time delay normal to keep the condensing unit from turning of and on to fast really save the life of the equipment
SOURCE: on my honeywell rth230b thermostat, sometimes when
They do that sometimes as a timing feature when going from heat setting the to cool setting or vise/versa. It should not do that when the thermostat is off and then you switch it to cool. Make sure the batteries in the thermostat are fresh. And make sure the thermostat is fully seated on the housing. Also check the wires are fully inserted into the connections on the thermostat housing and the wiring is correct.

The circuit breaker kicks off when the condenser kicks on. I guess my husband is finally calling for service. He is unemployed so he was going to try something himself.
I fully understand, being unemployed. Hope things work out god luck
