My fan just stoped it was running now does't work at all

The fan's main system control might have entered into it service mode. Contact the delaer from which the fan was bought.

No it won't.The brake switch is for brake light,interlock shift solenoids,transmission TCC controls,and stoping the vehicle, You fan blower has a completely different power supply that is independant from the brake electrical system, For you fan blower to operate its either the fan resistor blower or the fans control switch to the fuse

OK I am guessing this is a modular drive. Fault 39 is an IGBT fault on phase U and 40 is an IGBT fault on phase V. Unless you are experienced it's best to have a qualified service tech do the repair. However here are my thoughts. The IGBT fault may be caused by a dirty air filter located in the side panel. It's some where around 10" x 12". If the electrical panel filter is dirty you don't get enough cooling. The IGBT's get hot and over temp. causing the above fault codes. Check the filter and replace if needed. Next in top of the electrical and drive compartment is a fan. Make sure it is operating properly. If the fan is not operating again you get no cooling air for the IGBT's. I have seen customers open the panel doors and put a large fan blowing on the drive to cool it. I don't recommend this due to the fact the air is unfiltered and can get dirt into the drive and cause damage!. However some customers have to run and take the chance. There are also other items that can cause these faults. But as I said before determining whats wrong can be very technical. Does the display show any other # after fault 39 or 40 like 39 - 3 or 40 - 2. If so this gives additional info on the fault and tests to perform like checking the ID board or interface board. Good luck hope it's a filter.

I would check the drum rollers, idler pully and see if something has fell in where the fan is. Also check for lint build up. That is one of the biggest problems not keeping the lint screen clean. It gets stoped up and the fan blade can't turn. Also causes it to get too hot and could cause a fire. Last take the belt off and remove the drum . Run the motor for a short time with nothing hooked to it but the fan and see if the motor is making the noise. Have fun. Hope this helps.As far as I'm concerned you have one of the best machines. I wouldn't buy a new one too much trouble and expence.

Check the fuses/relays under the hood first.

Check the fuse first. If the fuse is good, then turn the A/C on and the fan should run continuously. If it does not then apply 12 volts directly to the fan. If it runs your Thermal Relay is bad. If the fan does not run the fan itself is bad.

If the fan was the problem and the compressor is now running , it should start getting cold.

Yes all you have to do is remove the motor and take the fan blades off as you will re use them. anything else just get back with me ken

grrr
