Testimonial: "I think this must have been the problem. I tested the gas valve by shorting it to the 24 volt tranformer which caused it to open. OK after that."

SOURCE: cuhp-45a-1 will not turn fan

There may be a small bi-metal switch mounted on the combustion chamber that allows power to the fan at a certain temp. Look at wiring diagram to find or follow power wire back to find it. It also may have a timer relay that may be bad. This unit is made by Advanced Distributor Products or ADP for short.

The heater turns on, but does not ignite. The fan runs for about 5-7 seconds then shuts off. I am assuming the heater needs a good cleaning?

Laptop wont start.


Remove the battery and unplug the power cord for 5 minutes, put in the either the battery or the powercord and power on.

if it doesn't power on, make sure the charging light is lit on the front of the laptop when the power adapter is inserted and plugged in properly.

light blinking when you power on means battery low / no power.

If the problem doesn't go away you need to contact acer for warranty service if you are outside warranty contact a local repairer.

Hyundai accent 2001 will not start all lights work radio works heater fan works battery in 3 months old when I turn the key all i hear is a humming sound for about 1 min. than nothing. weather has be


The humming would be the fuel pump coming on. It should only hum for a few seconds, then shut off.
Your problem is with the start circuit from the battery to the starter, or from the ignition switch to the starter solenoid. Check the connections at the starter (the big cable) for tightness.
Is the battery charged up enough to turn the engine over? Check by turning headlights on and observe while someone turns key to crank. If they dim a LOT, then either battery is too low, or the starter is bad and needs removing for testing. If brightness doesn't change, then the circuit from ignition switch to starter solenoid is likely not working. Check for 12 volts at the small wire to starter solenoid with key in cranking position. If you have power there, the solenoid may be bad. Remove starter for testing. If no power at solenoid in starting position, then either the ignition switch is bad or the neutral safety switch might be the problem, or the wiring from the switch to the starter solenoid is not passing current.
Good luck.

Heater will not start


Does the blower motor start when you plug it in/turn it on? It may take around 5 seconds if your heater has a HSI(hot surface igniter). If it does you need to check the igniter and the fuel flow. Either way, remove the top of the heater. You will be able to see the fan, igniter, and fuel nozzle. Turn the fan by hand to see if it turns freely. If it does, watch out for the fan and turn the heater on. Look for the igniter to start sparking (spark plug type) or glowing (HSI type). Next, use a flashlight to look for fuel spraying from the nozzle. If fuel isn't spraying, try cleaning the fuel nozzle and check the fuel filter. Watch out for the HSI, if you have one, they are very brittle and easily broken. If you still don't have fuel flow after cleaning the nozzle and the fuel filter, you may have an air pressure problem. Let me know and I will tell you how to check it. Don't forget to rate the answer if it works.

Minimax NT 400 TSI Heater problem


I bet that your 15 seconds of flame are more like 7 seconds. The time is very important. If the flame is not recognized after a specific time the valve is shut off. If the flame sensor is GOING bad but still make some rectification then you may get the issue you are having. I would start with the flame sensor and work from there.

Heayrt won't fire e4 can't hear fan runnung


I am not sure if you have gotten this issue corrected, or not, but the first thing I would try to do is to reset the heater computer system. This sometimes corrects and EO4 error code.

What you will do is open the right hand side door and find the POWER toggle switch, turn that off. Then find the CIRCUIT BREAKER for the heater and turn that off as well, then wait about 15 to 20 minutes. After waiting, you will turn the CIRCUIT BREAKER on first, then the heater. Try and start the heater up.

If the EO4 code comes back, there may be an issue with the heater. If the code does not come back and the heater starts, then the error code was what I call a "computer hic-cup".
