good afternoon friends, I have a doubt about the sensors that carry the minisplit, how to know its value if it does not have it printed on the board, what happens that I am repairing an electronic evaporator card of 2 tons at 220volt is mirage brand and the error that marks is F7 and I measured the resistance of the grounding sensor and it gives me 0.71ohm and I guess it is bad, but the detail is that I don't know what value to replace if it is 5k or 10k, the other sensor that brings me marks 4.6ohm I suppose that if it is good, another measurement I made was the voltage remove the two sensors and on both terminals it marks me 5 volt but when putting the sensors in one it marks me 2.5volt and in the other sensor the one of poso (the bad one ) I dial 0.75 volt and what I want to know is how to determine the original value of the sensor since it does not say anywhere. I appreciate your help.

Good afternoon, substitute for one of 5 kh. Regards.
