Most common cause is burned contactors in outdoor unit.Ants may fry causing the contacts to stick closed allowing outdoor to run non stop. Can you do some hands on troubleshooting and do you have a multi meter?
In outdoor unit there is a relay called a contactor. They have 230 volts supplying power any time breaker is on. When thermostat calls for AC, it sends 24 volts to the coil on this contactor engaging the contactor and allowing the 230 volts to flow through to outdoor fan and compressor.
If they burn and stick together the voltage continues to flow even when thermostat is satisfied or shut off which causes icing because e indoor blower has stopped.
Open the service panel on outdoor unit and take a look at these contactor and see if they are burned.
If they are burned ands stuck together yes. Simple to replace and cost about 20 bucks at any appliance parts store.
Yes, the phone call is an auto offer by the website. It is optional. We can continue here texting without the call.
That is correct.If you allowed coil to thaw, the outdoor can run without icing as long as blower is running inside. Just when thermostat reaches setpoint, turn off breaker to outside when the indoor fan cycles off until you replace the contactor.

Do you know where Appliance Factory Parts is located?
Never mind, they do not have them.I called. Let me see what I can find
Do you have any type of appliance parts store nearby.Most any of them should carry this.
You do not have to have that particular part number.A generic contactor will work.Just tell them you need a set of 30VA 230 volt ac contactors with a 24 volt coil.
They can be mounted using a couple of drill point screws if necessary as long as no wires are near the metal cabinet.Otherwise you may have to either order online or call a local contractor who will have them in stock, but that will of course be more costly as he will want a service call to install them.
