Question about Carrier Heating & Cooling
We are having to turn it off and on at the outside unit so that it works, the remote is working it's just not sending a signal to the air con
If you get a mobile phone and select its camera, then look at the LED at the front of the remote thru the camera, press some keys on the remote unit and you should see the LED light up on the remote on the mobile phone camera screen (it picks up Infra Red which we can't see). this will let you know if the remote control is working. if it is, the receiver at the indoor unit is either covered with something, check thoroughly, or the receiver is faulted, replace via technician.

Yes, if the filters are clean, the coils are clean, and it is still freezing up in cooling mode, then it is low on refridgerant.

I recommend putting new batteries in the remote. If that alone solves your problem great. If not, get back and let me know

there is no fuse on your condensing unit outside. pull the disconnect to kill the power to the unit and take off the removable panel above the 2 service valves. there will be an oval shaped capacitor that is marked herm and fan. there will be a rupture disc on the top that may have ruptured. also inspect the low voltage wiring(will still be hot unless you turn off the switch at your furnace). this low voltage wire operates a magnetic coil on the bottom of the contactor that closes a high voltage circuit to the fan and compressor.
