C0F24 Code is the code for the sensor that monitors the drum. I would remove the drum cartridge two black screws pull out the drum assy. Remove the drum be careful do not nick or harm the drum the sensor is located on the left side of the to the rear of the of the drum looks like to little eye of a bug. Dust with a brush NO VACUUM static could destroy it. Re-install drum and re-install cartridge. When the last time a PM was done Developer replaced and Drum replaced?
Yes,could be your blower resistor is bad,it's right next to the blower motor,it controls the blower motor speed,easy to replace. Duralast Blower Motor Resistor Just took a guess at the model type since you didn't state,wow,high dollar price,guess it comes with a Mercedes,paid about 18 bucks for mine on my 85 Nissan.
The fan has a setting for high speed, low, and off.Fan only running at low speed.This indicates problem towards.1) the fan motor.2) The loose fan wiring.3) The fan switch.IN the unit there is a motor for fan.If the motor gets weak or short. The fan will run but only at low speed.Because at high speed the motor will require more power to run.In this case motor needs to be checked and replaced.The other possibility is the fan wiring.There are two wires going from fan to motor and two going from motor to power board.If any of this wire is got loose or getting short then this will stop the fan to run in high speed.In this case the wires needs to be checked and reconnected properly.In the unit there is a switch internally.When you select the fan to high speed mode the switch goes up. when you select the fan to low speed mode the switch turns down.But if the switch is faulty or got worn out.Then it will not move properly up/down.In this case switch needs to be replaced.IN some brand models the High speed and low speed are directly controlled from front control panel.There is no switch in that models.In that case the control panel needs to be checked and replaced.Thanks. keep updated for any more query.you can rate this solution and show your appreciation.
some manufacturer already attached a variable speed controller when you purchased them, meaning the unit requires this control, but in your case when you purchased it, it does not have any, meaning they sell it to the market as ready to use, so why install additional control?
There might be an installation error during the assembly, so all you have to do is just interchange the wire connected to the control from LOW, MEDIUM and HIGH, it is a trial and error thing but it won't affect or damage your unit, maybe your high speed connection was connected to a low speed control, so just inter-change it. Remove the variable speed control
well the growling noise is more than likely a worn bearing in the blower motor it would be better to replace the whole motor, and on the fan speeds the blower motor resistor is the cheaper solution to take and more likely however if the resistor doesnt fix it then look at the control unit in the dash as the problem but like i said more than likely the resistor will fix the problem
The indoor blower motor is sometimes a 3 speed motor.The heat usually works on low or medium speed.But the a/c is usually on high speed,this gives greater air flow across the evaporator coil to give you better cooling,also better air flow at ducts.These speeds are usually wired through a relay in the inside unit (air handler).They can be changed.If you go to thermostat and put the fan switch to "on" the blower should operate on "high" speed.With the fan switch set to "auto"the operation will determine the fan speed.Hope this helps.

Compressors on these units runs at only one speed. The change to high cool is only a change in blower speed moving air faster over the cooling coil. I would have the running capacitor for the fan motor checked. A bad capacitor can cause your type of problem. The other problem could be that the high speed winding in the fan motor is bad. Try it operation in the fan only position through the two speeds. If it works in the low and high speed for fan only your problem could be in the selector switch.
You may be right in looking at the motor. It uses a different speed on heat than cool. The heat cycle uses low speed, usually red. Some manufactures use blue (medium). Cool uses black, high speed. If you are confident, switch the low speed wire with the high speed and see if this changes anything. If the fan motor isn't the problem, check the other setting (cool) if the overload trips, you may need to look into a new capacitor or compressor, if so, you can install a hard start kit. these are start boosters, and are inexpensice, sometimes they will give another year out of the comp. but I've put them on and they have lasted 5 years.
