Fan speed control electrical box burned up in less than 60 days need to replace it. Model: UC7067RK

On your control card for your furnace check the fan motor taps for power supply with a multimeter for having the proper voltage. Most control cards have two wires to control fan speed in heat mode and another speed for cool mode operation. You can locate the normal wire colors on the control schematic (electrical drawing) to see if the wires are connected properly.

If your motor has been wired improperly you may have already damaged the windings in the motor and you will need to replace the motor. It only takes about a minute at the wrong voltage to burn a motor up.

You may have a bad capacitor. Most fan blower motors operate at different speeds in heat mode than cool mode and get their voltage applied to different windings in the motor to get different speeds. Most windings need a capacitor to get current and voltage back in phase to increase efficiency, but if the capacitor is bad the motor can run in one mode and can even reverse direction in another mode.

Sounds like I just figured out your problem, get a new capacitor.

Fan Control The PCM monitors certain parameters (such as engine coolant temperature, vehicle speed, A/C on/off status, A/C pressure) to determine engine cooling fan needs.
For variable speed electric fan(s):
The PCM controls the fan speed and operation using a duty cycle output on the fan control variable (FCV) circuit. The fan controller (located at or integral to the engine cooling fan assembly) receives the FCV command and operates the cooling fan at the speed requested (by varying the power applied to the fan motor).

Linear speed increase from 50% to 100% Greater than 90% but less than 95% 100% Greater than 95% but less than 100% Fan off
For relay controlled fans:
The PCM controls the fan operation through the fan control (FC) (single speed fan applications), low fan control (LFC), medium fan control (MFC), and/or high fan control (HFC) outputs. Some applications will have the xFC circuit wired to 2 separate relays.
For 3-speed fans, although the PCM output circuits are called low, medium, and high fan control (FC), cooling fan speed is controlled by a combination of these outputs. Refer to the following table.
If you don't understand these thing's listed above your best bet is to take your vehicle to a qualified repair shop . Have the vehicle checked for DTC'S - diagnostic trouble codes !
If

It would help to know the make and model. Different manufacturers put them in different places and mount them different.

The fans heat speed is low speed and the cool speed is high speed. High speed is controlled by the fan relay normally open switch, the low speed is controlled by the temperature delay or time delay.
see diagram

The blower fan uses a voltage ballast block to control the different speeds. Sounds like it needs to be replaced. However, usually the highest speed still works, but not necessarily.
This is an inexpensive part and usually easy to change.
The voltage ballast issue. this is an electrical block which controls voltage to change fan speeds. Usually found under the passenger side dash, right in the air flow comming from the fan and inside the air flow housing. Usually held in by 2 or 3 screws with a connector and 3-4 wires sticking out. this should be under $20 to buy and quite easy to change, if you can find it. Try behind glove box etc. Do not test the new one without it being in place, as it may burn out very quickly without the air flow to cool it.
Good luck

I need a RHINE fan speed control model uc7058ry 7058gy-05 part. Please tell me where I can get one

Your issue is most likely a faulty speed control. The part is integral to the remote receiver in the fan housing. You can purchase spare parts for this fan through Home Depot (Hampton Bay) Service at 800-654-0688.

The receiver is located in the upper portion of the housing for the fan motor. Look for a semi-circular black control box (usually manufactured by Rhine)

dominion electric might have it if you really have to have that fan but best to get new one same work you got to bring it downand work on it ...less work buy new one less head ache ....

if you can identify what type and model electric motor your fan is using, visit Grainger or Harbor Freight then ask them if they can query and match your fan's electric motor model with a replacement.

Good Morning!
What youre experiencing could be a result of a faulty oven temperature sensor, a faulty oven control board or relay board. Youre more than welcome to send both the main control board and relay board for evaluation. Fixyourboard will test and repair both as needed for less expensive than buying new, and include a two year warranty.
