The 700 will not start for this season. I put the humidistat in the test position and did not hear the click and the fan did not kick on. I called for heat, tested the electrical connections. Nothing. The fan and water control work as I crossed the two yellow wires coming out of the water control. I use the humidistat in manual setting. I am assuming that the humidistat is the issue. All worked well last year.
Reason why I asked they sometimes have a problem sensing current and you may need to wind the wire twice instead of one pass. If you jump the wires at the humidistat and the unit turns on its either the stat or you may want to do a relative humidity check on the house to see where your at
Best regards,

was tha fan on while you wer in test mode if so the relay is working. If the fan was not on the relay is stuck in the closed position and will run even without the main blower running. I would check the humidistat for voltage at the hum or H terminals for 24 Volts when the unit is set higher than the relative humidity of the house.
Sorry about the typo's its late here and I have been working 14 hours a day fixing problems just like yours

Yes I installed it when I installed the humidifier.
Robo: I tried to wrap the wire around the sensor but I do not have enough wire. I used electrical tape to insulate from metal. How do I know if the sensor is bad? When I used to put it in test mode, I heard a click and then it would start up -- without the heater running. Suggestions?

Still having problems with Apirlaire 700:
Unit will only start when I cross the two wires that come out of the water solenoid. I have installed a new Model 50 electric sensor. I have checked my connections. No power to humidifier. When I put the humidistat in test mode, nothing happens.
Suggestions?

Do you have a relay on the unit that is in the blower area? looks like a little black box that has a metal Ushaped end that has a wire running into it
