It may seem to high for winter operation but you need it in summer for adequate air flow. have to check wireing diagram and see which wire they are using off fan relay

SOURCE: fan motor slow on a/c

If the fan motor has a capicator it could be bad. A bad cap will pull the motor down. If there is no cap then the motor beatings could be going bad. this can be checked by matching the motor amps with the rated amps on the unit information tag.

    SOURCE: replacing indoor fan motor in the split system unit

    These have to be pulled out sometimes forcefully. There should be a keeper bolt that needs to be loosened, i usually wire brush the shaft to get any rust off, then spray with wd40 then support fan blade from the underside with one hand and bang The shaft downwards with a hammer. Once it's flush I stick a screwdriver in and hit it out the rest of the way out.

    On a 2007 lincoln navigator the a/c fan motor will not shut off. the fan adjustment bars are showing slower but still the fan is on high

    The fan speed reostat is broken or the switch itself is bad. Try replacing the switch first because the motor speed reostat is part of the motor itself. $$$

    Fan will only blow on low when heat is on

    your fan most likely is wired for low speed for heat which is common. this should be determined when furnace is set up properly. motors that aren't modulating motors and are multispeed motors typically have low medium and high taps that come off the motor and go to the corresponding relay on the board. low and medium speeds are used for heat and high and medium speeds are used for cooling. but only one speed for heat and one speed for cooling many times medium never gets used. im not familiar with klimaire is this a mini split system and not a regular air handler. cause speed control should be adjustable from the remote. if its a split but if not reaching desired speed due to a malfunction in the units could cause it to run low speed just to maintain the temperature exiting the indoor unit.

    Condenser fan does not come up to full speed.

    These Ptac units are advance system that are designed with variable speed motors that modulate in order to save energy, This is normal operation, because starting a motor at a lower speed rather than the conventional high speed will save energy, which translates to saving you money. As the load increases (heat) on the condenser coil, the fan will ramp up accordingly.

    Kenmore over the stove microwave,model # 721.62629200,only low speed fan works on the keypad,no high speed fan.

    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 can rate this solution and show your appreciation.
