Hello - I am not changing the dryer. However, if I remove this switch, will all the Freon leak out? I was assuming there might be a check valve. Thanks.There may be an assumption that when removing that switch you're also changing the dryer. In that case, unclip the sensor and remove once the dryer is removed.
They do make sockets with notches for wires for O2 sensors but those would be too big.
Is there really no room for a stubby end wrench or something similar? small crescent wrench?
