Vacuum Motor Circuit Board Single Motor 15amp 120v

Product Details

Vacuum Motor Circuit Board Single Motor 15amp 120v

Excellent replacement for all single motor 110 volt central vacuums with a separate relay/transformer/breaker or with a single control board. Some retrofitting may be required.

Compatible and Durable. This very durable, industry standard, Alutron control board contains a relay, transformer, 15 amp mini breaker, and two pairs of low voltage leads (wire set and black tower with flag terminals).

Installation. Circuit board control module is 2" high from board to top of reset button. The reset button and low voltage stems are threaded. When put through holes in the body of the vacuum, the two stems hold the board in place with two included thin mounting nuts. If you don't have a proper hole for installation you can use a drill and step bit to create proper holes. NOTE: It is recommended that an electrician should install this board. It should take them less than an hour.

Wiring. Click on the photo and print it to use as a wiring guide. The connections are 1/4" flag terminals. We recommend purchasing quarter inch female flag terminals to put on the motor and power cord wires, or buying our wire set with terminal ends and striping them into the wires with wire nuts. Wiring locations on the board:

  1. “LINE”: The 110 volt line (usually black) from the power cord
  2. “NTL”: The neutral wire from the power cord (usually white)
  3. “MOTOR”: Connect either wire from the motor to this contact
  4. “MOTOR”: Connect the other motor wire to this contact. Vacuum motors are polar neutral it doesn’t matter which motor wire goes to which motor board contact.
  5. Black Tower: The low voltage wires from the home will attach to the two 1/4 inch male flag connectors inside the black tower part of the board. It doesn’t matter which wire goes to which side.
  6. Yellow Wires: Attached to the board are low voltage wires that can ignored or go to an on/off low voltage switch on the side of the tank.

ATTENTION! Beam, Frigidaire, Eureka, Honeywell Control Board available HERE.

Product Details

110 volt Transformer (large)
Transformer used in some brands and models, such as: SV, SVT, S3, S5, C210, G23. Can also be used for smaller models. BUT NOTE this transformer must be used now with the only replacement relay we sell for all our vacuums. The #242 Relay must be used with the #232 Transformer. To wire correctly see the diagrams in #242 relay and note that you need to choose either the white or red or orange wire (white is for 110-120 volt units, Red is for 208 volt, and Orange is for 240 volt - these instructions are on a sticker on the top of the transformer).

28 amp Relay (replaces all relays, requires large transformer)


28 amp Relay
28 amp Relay

Product Details

28 amp Relay (replaces all relays, requires large transformer)
RELAY MUST BE MOUNTED RIGHT SIDE UP TO WORK (sticker/wording pointing up). See our Relay Bracket (usually below this relay listing) to make upside down applications right side up.

This relay replaces the smaller ones previously sold (#240 and #241). It ONLY WORKS WITH LARGE 24-VOLT TRANSFORMERS (PART #232 if 110-120 volt or #231L if 220-240 volt) which are typically not in machines under 20 amps - regardless of what you read elsewhere on this website, this relay requires the larger 24-volt transformer. You can replace your transformer with a heavier duty one.

The 242 relay works with all kinds of 110 to 240 volt motors, and all mini breakers. It works with an electrical set-up similar to the ones in the following photographed diagrams. Click and print a diagram for wiring a SINGLE MOTOR VACUUM, or DUAL MOTOR VACUUM under 16 amps, or DUAL MOTOR VACUUM over 16 amps. (When in doubt on amps use the diagram for the larger amps.) Use 14 or 16 gauge wires and put on 1/4 inch flag terminals (all available at hardware stores). Use 12 gauge wire for dual motor setups over 17 amps.

To mount it you MUST HAVE 4 x 2.5 inches of space. Do not allow any metal on the relay (besides the bottom) to touch any metal parts on the vacuum except the wires. There are several "feet" on the bottom to use screws (not included) to secure it.

Replaces Omron Relays. Has MFG# DP2020A5021. NOTE: Mid-2004 circuit boards became more popular.

RFX Central Vac Wireless Remote Kit (not RF915) Part#145

This product is no longer available but here for customers to find and be educated on the latest technology. See the RF915 Remote Frequency (RF) controls for the easiest way to bypass damaged low voltage wiring and remotely start your vacuum unit. Click here for RF915 components.

The RFX range was similar to a vehicle key fob - about 150 feet depending on wall thickness and barriers. The 400 mhz was sufficient for nearly all homes. Each receiver was programmed separately so you can have multiple systems in adjoining homes and condos. Extra key fobs are still sold separately. Not compatible with LV11 parts.

RF 915 Receiver - Radio Frequency

RF 915 Receiver

Product Details

RF 915 Receiver - Radio Frequency
RF915 is the most reliable fix for homes that do not have or lose their low voltage connection to turn the vacuum suction tank on and off. RF915 uses a receiver and a unique electric hose with a sender or remote fob clicker. In addition, an RF915 Automitter can be used for kick vac ports. There is also a signal repeater for extremely large homes.

Use this receiver as part of the RF915 central vacuum wireless solution. Only one needed per home and is usually installed near the central vacuum unit connected with a low voltage wire. The receiver can be installed elsewhere so long as the low voltage wire connection to the vacuum tank is in place. The receiver is plugs into 110 volts. Each receiver can be paired with up to 10 hoses.
