How do I read the error code on a TCL AC — it's showing an E, F or P code on the display?
Our TCL split AC is showing what looks like an E or F code on the indoor display, and sometimes a light just blinks instead. I don't want to start swapping parts off a random online list. How do I actually read a TCL error code properly, and how do I tell the ones I can reset myself from the ones that really need a technician?

Read the code before you touch anything — it's the step that saves a wasted call-out. TCL units flag a fault one of two ways: on models with a screen you get an alphanumeric code (commonly E-, F- or P-codes) on the indoor unit; on models without a display, an indicator LED blinks a count that you read as the code — the number of flashes and the pattern ARE the code. Either way, step one is the same: photograph the display or count the blink sequence before you clear anything, and note whether the indicator is on the indoor unit or the outdoor board.
The honest caveat: exact code meanings vary across TCL series (the split ranges don't all share one table), so the only real authority is your unit's own manual — match your model number (on the side sticker) to the manual on TCL's official site. Skip the generic "TCL error code" lists online; they blend different series and contradict each other, which is exactly how the wrong part gets replaced.
For what you can clear yourself versus what needs a pro, go by the symptom, not a guess at the code. If it clears on a proper power-cycle (off at the isolator for a few minutes, then back on) and cools normally afterwards, it was most likely a transient protection trip. But if the code comes with no cooling, ice on the pipework, the outdoor unit not starting, or it returns the second you reset it, that is a sensor, pressure, compressor or board fault — stop running it, because forcing a unit through a genuine protection trip is how a compressor dies. Same read-the-code-first logic as the Samsung and Gree threads and the general error-code guide. If a code keeps returning after a clean restart, AC repair and maintenance can meter it on the tools and confirm what is actually tripping instead of guessing. Photograph the code before you clear it.
In our building we get these across a few TCL units. Two habits save real time: photograph the code AND note the model number off the side sticker before you call anyone, and try one clean power-cycle at the isolator first. Half the "faults" we log clear on that restart; the ones that come straight back are the real jobs.
