Contact the manufacturer and inquire if they repair or replace the units with freon leaks. Also ask them if they can refer a repair shop near the town you live in. Quite simply, putting more freon in it will leak out and it will keep freezing up. Fix the leak. >>>> More times than not the leak is not in the coils. It could be any one of the 4 piping connections (2 on the furnace and 2 on the condenser) and if the installer did not use a single line set, any of those additional joints as well or somewhere else in the condenser. Coil leaks are rare for the most part. Usually the hardest part of leak repair is finding it.
Freeze-lining refers to the accumulation of solidified material, such as slag or metal oxides, on the refractory lining inside a furnace in the smelting area. This can obstruct the flow of material and heat transfer, leading to decreased efficiency and potential damage to the furnace lining. Regular maintenance and proper operating conditions can help prevent freeze-lining issues.
I have this same type of sill furnace and the filters goes on the inside closest to the blower.
The water inside a hose can freeze.
The function of a furnace fan limit switch is to regulate the temperature inside the furnace. It helps control when the fan turns on and off based on the temperature of the air inside the furnace. If the switch is not working properly, it can cause the fan to run continuously or not turn on at all, which can lead to overheating or inefficient heating in the furnace.
A thermometer....
He was placed inside of Laozi's 8 Trigram furnace.
The function of a furnace limit switch is to monitor the temperature inside the furnace and shut off the burner if it gets too hot, preventing overheating and potential damage to the furnace.
Make sure the condensation water, inside the furnace, is draining out. You probably should check the coil, inside the furnace and clean it.
The location of your furnace filter is typically found near the air intake or blower compartment of your furnace. It is usually located either inside the furnace unit itself or in a nearby filter slot.

The function of a furnace heat sensor is to detect the temperature inside the furnace. It contributes to the overall operation of the furnace system by ensuring that the temperature remains at the desired level, allowing the furnace to function efficiently and safely.
The Lennox furnace filter is typically located inside the furnace unit, near the blower motor. It is usually behind a removable panel or grille.
