Could a failing High-Efficiency Pleated Air Filter cause the TRANE XR16 to have symptom: Ice On Coils Blowing Warm?

Accumulated particulate matter on the filter media increases static pressure and reduces CFM (cubic feet per minute) across the evaporator coil. Without sufficient warm air to facilitate the phase change of the refrigerant, the coil temperature drops below 32°F, leading to ice accretion that eventually blocks all thermal transfer.

Could a failing Thermostatic Expansion Valve (TXV) cause the TRANE XR16 to have symptom: Ice On Coils Blowing Warm?

The TXV regulates refrigerant flow based on cooling demand; if the internal sensing bulb loses its charge or the internal needle becomes stuck, it restricts refrigerant flow. This starvation causes a localized pressure drop within the coil, lowering the refrigerant's boiling point below the freezing point of the condensate.

Could a failing Evaporator Coil Assembly cause the TRANE XR16 to have symptom: Ice On Coils Blowing Warm?

Micro-fractures or formicary corrosion in the copper or aluminum tubing lead to a slow loss of refrigerant. According to the Ideal Gas Law and pressure-temperature relationships, a reduction in refrigerant mass results in lower operating pressures, which causes the coil to operate at sub-freezing temperatures until ice encapsulates the unit.

What is the most likely root cause for a TRANE XR16 with symptom: Ice On Coils Blowing Warm?

Accumulated particulate matter on the filter media increases static pressure and reduces CFM (cubic feet per minute) across the evaporator coil. Without sufficient warm air to facilitate the phase change of the refrigerant, the coil temperature drops below 32°F, leading to ice accretion that eventually blocks all thermal transfer.
