Question about Aprilaire 700 Humidifier

1 Answer

Aprilaire pump motor rattles violently

The pump that pumps the condensate out to the sink rattles violently and loudly when it pumps. This started happening a couple weeks ago and has gotten worse as time has gone on. I don't see a way to turn off the pump or disconnect it as it appears to be hardwired into the power supply.

When I pour water into the pump, it seems to be a little quieter when it turns on. Also, there is water that has dripped onto the top of the furnace. I don't see any obvious spots where it is coming from.

The water basin that receives and pumps out the excess water on my Aprilaire 600 humidifier runs incessantly, even when very little waters in in teh basin? Is there an easy fix? thank you


If you are referring to a condensate pump then the float might be stuck and causing the pump to run continuously. The best thing to do is turn off power to the pump and clean it out and make sure the float is free and not stuck.

Have a large new house with lots of vinyl clad wood double hung windows on a lake temp today this am is 0 F we have a HRV system house temp is 66 downstairs and 58 upstairs heating with a heat pump and...


Really not efficent to run a heat pump at those temperatures. Below freezing is not good for the compressor in the outside unit. The humidity in the house with the low temp. is causing the condensation on the windows to freeze. Kinda like an air conditoner does in the summer without the freezing humid air from the house goes over the cold a/c coil and the moisture condensates on the coil running down to drain pan. raising the temp. in the house and lowering the humidity should help. I would also recommend running the electric heat in low outside teperatures.

Aprilaire 760 furnace humidifier makes a loud screeching sound.


A bad circuit board should not make any noises. A bad solenoid valve could make a loud buzzing noise. If the noise is a squealing noise then you have defective bearings in the blower motor.
If you disconnect the low voltage wiring from the solenoid valve and you still hear the noise, then its not the solenoid valve.
