Hi.

Try first resetting the unit by disconnecting power to the AC for five or ten minutes. Also reset remote by removing batteries.

If that does not work, then the problem is likely a faulty variable speed fan. The repair is done energizing the fan at different speeds by jumping its contacts.
If fan works, next step is reading Volts from contacts on control board. Testing must be done by a technician.

If the unit is faulty contact Coleman to get the spare part or to book repair, see: Coleman - Air Conditioning.

Blower just started staying on - furnace has been turned of for 6 months


This is a diagram of a blower relay and a fan motor, the normally closed fan relay switch goes to the low speed which is the Heat speed, the low speed is controllled by a temperature delay depicted in the low speed circuit.
The normally open fan relay switch goes to the high speed, which is the AC modes speed , also if you run the fan continuously via the fan switch on the thermostat this is also to high speed.

I suspect the temperature delay's on setting is being reached thus cycling the low speed of the fan.

Ceiling fan stuck on low


in order for the remote control to work properly the fan has to be on its highest speed using the pull chain ... after setting the pull chain in the proper position you can tie up the chain or remove it to prevent others from changing the setting .. the remote will control the speed from then on ..

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 query.you can rate this solution and show your appreciation.

Fan will not run on high. Compressor runs fine but the fan will not run on high. Works fine on low and med.


It's the mode switch contactors for the high setting just overview the wiring of the high cool or high fan contactors if it's not there check all leads for the high fan or high cool circuitry.

Fan stuck on LOW speed


It seems to me you have a faulty switch or the internal wiring is wrong. You can access the switch from the bottom of the fanwhere the light kit is connected. the wiring could have gotten mixed up when the light kit was installed.

Hunter fan with remote control was 3 speed, now only 2 speed


It sounds like fan motor is okay. There are two motor windings -- one low speed, one medium speed. Low winding gives you low speed, medium winding gives you medium speed, both windings give you high speed -- so I would say if you get high speed, both windings are good.

The remote (the hand held transmitter) controls the speed by raising and lowering the frequency of the current which is 60 cycle coming to the fan ceiling box. If the fan speed -selector switch (usually a pull switch) is set to high, when the remote (transmitter) signals the receiver to change speeds, the frequency of the current is changed by the receiver (the receiver is usually in the fan housing).

Sounds like you'll need to replace the remote system -- these come in sets, both transmitter and receiver, and cost about $30. If you're not experienced with wiring fans, you should get an electrician to do the job.

the control board resistor for the fan control has gone this controls the voltage to the fan, it will need replace. with this not working the power goes straight to the motor.

Casablanca fan speed problem


If this fan has a pullchain that also controls the fan speed, and you have a remote, the pullchain has to be set for the highest speed. If it is set at medium or low, it will mess with the remote operation. Note: usually high speed is the first pull after the "off" position.

Hampton Bay Ceiling Fan At Slow Speed


I recently replaced my hampton bay fan for the same reason (slow at all speeds) and discovered scorched and melted capacitors and wiring inside the fan. My suggestion is to stop using fan and replace immediately.
