Hello will this part repair my particular unit with a ch 46 error code? Thanks.
For model number LMAN095HVT
Hi Daniel,
Thank you for your question. That error code means that there is an outdoor suction sensor fail. This would be the part that you have to test. Disconnected it from the power control board, it should read 10 ohms at 10 degrees C, and 4 ohms at 30 degrees C. If the part matches these readings then it is okay and you will have to replaced your power control board. If it does not, you will have to replace this thermistor. Good luck with your repair.
