How does a front defroster work in an air conditioner? The front defroster uses the same blower motor, fan and venting system that the heating and air conditioning system use. Air passes through the heater core and then dry air that has been run through the air-conditioning evaporator is added to help remove the moisture from the windshield. What causes a defroster to become inoperable? Old Age: As defrosters age they can lose their conductivity which reduces their ability to conduct an electrical current. Repeated cleaning, the sun and objects rubbing over the grid will eventually wear the grid down...

What happens when you overcharge a condenser? Excessive Condenser Heat Yet overcharging will greatly increase the temperature of the air being pushed out of your condenser unit. This heat stems from the higher operating temperatures of the refrigerant itself. A portion of it also comes from the overworked compressor motor inside of your condensing unit. Can a dirty condenser cause AC freeze up? Dirty coils can cause freezing because the layer of dirt on top of the coils can prevent them from absorbing the water fast enough. Bi-annual checkups from your local HVAC professional can keep your AC's coils clean....

What are the trouble codes for an a solenoid? The trouble codes related to this, the "A" solenoid, are codes P0750, P0751, P0752, P0753 and P0754 based on the specific malfunction that alerts the PCM to set the code and illuminate the Check Engine Light. These codes will also be associated to the A, B or C solenoid circuit. Do you need a solenoid valve for a fan clutch? Freon Pressure Switch, and N.C. Solenoid Valve are the only controls absolutely necessary for Fan Clutch operation. The N.C. Manual Switch, Air Pressure Switch, and Indicator Light are all optional controls...

Which is better exhaust brake or engine brake? When it comes to performance, the Jake brake is a lot more powerful compared to the exhaust brake. A Jake is to exert braking power that is slightly over the rated power output of the engine; in comparison, an exhaust brake can only do somewhere between 60 to 80 percent. What is the difference between exhaust brake and retarder? A retarder is a hydraulic or electromagnetic device fitted to the output of the transmission or on the driveshaft itself. An exhaust brake is a device that opens the exhaust valves at the...
