An HVAC tech was at my mothers home doing a routine maintenance when his elbow brushed against the ac line. He received a shock and started to investigate. He found the outer casing of the AC was reading 105 VOLTS???
after removing everything giving a load he still could not find out why? but he replaces a single pole lennox a the shut off with a double pole. That seemed to mostly fix the problem. There is still some minor voltage , i think he said 15volts. We dont know why the breaker did not trip. Obviously one of the legs is making contact with something it shouldnt.
Has anyone encountered a similar situation? This guy and another veteran of HVAC were baffled.
