HUMIDASTAT INTERNAL RED LIGHT USED TO BE ON AND UNIT WORKED. LIGHT STAYS OFF AND UNIT DOES NOT WORK. WHEN I DISCONNECT AND REATTACH HUMIDISTAT POWER LINES, RED POWER LIGHT GOES ON FOR A SECOND AS DOES THE REPLACE PAD LIGHT. THEY BOTH GO OFF AFTER A COUPLE SECONDS. HUMIDISTAT SEEMS TO NOT SUPPLY POWER TO THE SOLENOID. WATER LINE CLEAR. SOLENOID DOES NOT CLICK AS HUMIDITY SETTING CYCLED.

BMW 528i 2008, Won't Start, Won't Crank, but still power into instrument panel, radio, light, AC and computer.

I have the same problem, I am able to get the car to start by jumping the car battery red terminal to the engine compartment red terminal (this bypasses the Internal Battery Management system), the car stayed running after disconnecting the jump. I then tried disconnecting the black battery terminal secondary which is supposed to control the IBM system, but that did not work. There is supposed to be a unit under the spare tire that could be a problem.

I have a HoneywelI Enviracare Elite whole house humidifier. I have no power to the thermostat. The wire goes into the furnace and is attached to a control board. The furnace is working. Humidifer is n

Most of the humidifiers are run by 24 volts AC. disconnect the power wire to stat on circuit board and check there with meter and connect to low voltage ground for 24 volts, I'm assuming the two wires that power the humidistat are red and white.typically red is used for power. most likely you have power if the red for the stat is connected to the W on the board and the heat works, but the humidifier only works while heat is on.the next thing in line is the humidistat , it's a switch so if there is only two wires going to it take them off the stat and connect together, if furnace is on heat and running and stat wires are connected it will send power to water solenoid, if its not working yet the problem lies in the water solenoid if you have 24 volts at the two wires at solenoid.check while disconnected, do not connect those two wires together or a 3 amp fuse will blow on the furnace board. if you have 24 volts there then the valve may be bad or the valve may be stuck or clogged, loosen water supply line to make sure water is getting to valve. I spent many years working in the HVAC industry.

PIONEER TV RED LIGHTS

Hi Miquel.

If the unit does not start but stays in standby with the red light on, then the TV is in forced standby mode because an internal problem has been detected.

Try disconnecting power cord for ten minutes. If that does not help, then the TV must be tested and repaired.

Regards.

My 550 is bone dry. I've cleaned the small in line screen blew out the line. How do I know if its the selinoid or humidistat?

Turn off the water to the humidifier

Disconnect the water line to the inlet water valve (the solenoid), catch any excess water or drips in a small container

Turn the water back on slowly and see if water flows through the open line (the one you just disconnected - catch the water in a small bucket)

If you have water to the valve, it's probably the solenoid valve - you can test this by reconnecting the water line and turning the humidistat all the way up. You should hear a click as the solenoid tries to open. If it clicks and no water comes out it's the valve. If there is no water to the valve, you'll need to determine the reason(s). Although not every water valve has one, check for a plugged inlet screen at the entry to the water valve (solenoid)
Sometimes the small line tap valves commonly used with humidifiers can plug up or malfunction. If you try to repair or replace the tap valve, make sure the water is turned off.
If no click, it could be the humidistat or there is no power to the unit.
If the humidistat is bad, you won't hear any click and no power will be sent to the solenoid valve. In that case, the humidistat may be defective.

Depending on your comfort level and knowledge, you can try applying power directly to the valve by bypassing the humidistat, but only try this if you are comfortable working with electricity. The voltage should be around 24 volts (in the USA) , which is low, but requires some knowledge.

Wii menu will not come on when power is turned on.

Do you hear any sound when you power the console on? I assume it used to work fine? Try disconnecting all cables from the back of the Wii, waiting about 90 seconds, reattach all cables and power on. Does the power light go to green?

Constant Red Light on Control Panel Circuit Board

The red light under the cover of the humidistat is fault light. This light typically indicates that there is an issue with your connection at the two wiring terminals labeled ODT on the humidistat. I would recommend checking to confirm that there is something currently connected to the two terminals. As a side note these two terminals can not be jumped out with a jumper, and must utilize either the outdoor temperature sensor (part 8052) or the manual mode resistor (part 4336).

Doesn't run

When a humidifier doesn't run, it generally means it isn't receiving electrical power or the controls have automatically shut it off. 1) Be sure it's plugged in to an outlet that works and that it's turned on. Check the electrical receptacle for power, using a working lamp, appliance, or voltage tester. 2) If the receptacle seems to be dead, check the circuit breaker or fuse that serves the humidifier's circuit. 3) Check the setting on the humidistat. If it's set lower than the room's relative humidity, the humidifier won't go on; in fact, it may take several hours for the humdistat to respond to the room's changing humidity. 4) Be sure the humidifier's reservoir is full of water. 5) Unplug the humidifier unit. 6) Check the power cord. If necessary, repair the cord. 7) Remove the humidifier's cover panel. 8) Remove the humidistat and check it (as shown below). Replace it if necessary. 9) If it still doesn't work, call an appliance repairperson, take the unit into an appliance repair shop, or replace the unit. To check the humidistat, you?ll need a volt-ohm meter. A humidifier?s fan vaporizes the water in the reservoir and blows the water vapor into the house or room. If you need to check the fan, unplug the humidifier, remove the control panel, and lift the lid. Tighten the fan hub with pliers if it is loose; this should take care of rattles. If the fan doesn?t spin easily when you try to move the blades by hand or if it is still noisy, lubricate the motor bearings with oil. To establish whether power is reaching the humidistat when you know there are no problems with the plug or switches, unplug the humidifier, remove the control panel, and lift the lid. Test it with a volt-ohm meter set to the RX1 scale (or to K[omega symbol] or [omega symbol] resistance on a digital meter). Clip the meter to the humidistat terminals. The meter should jump if you turn the humidistat from high to low. If it doesn?t, you?ll need to replace the humidistat or return it to the manufacturer.
