Just remove the top panel (the one you open when you vacuum the condenser/compressor area) and you will see the top of the switchplates. They are very easy to remove - I think I remember just a little pressure and the locking pins allow you to push the switch through to remove it. This part is simple to replace and not expensive to buy. Make sure you turn the unit off prior to removing and disconnect the wire harness connected to the switch before removing it.

Check the light bulb fittings are not corroded or disconnected.
Otherwise a long wire with clips on to check the circuit is complete from fuse to each side of the lamp fitting, or in between

    Hotpoint quadrio fridge bulb not working

    Hello Donna;

    My name is Peter. I am a retired field service refrigeration technician.

    Ok, lets fix the problem:

    1.) The light bulb is a special bulb designed to operated in cold temperatures. Some food markets carry them. They cost $10.00-$12.00 each. A normal household bulb will fail.

    2.) Assuming you have the correct light bulb. With the refrigerator door open, is the light on? Push the light switch, does the light go off? Light switches either have a small whit plunger or a curved actuator.

    3.) Ok, before we assume a bad switch. Unplug the refrigerator. Remove the light bulb. With a flat head screw driver, lift the copper contact in the bulb socket just a little bit, to make sure the copper contact is not depressed and not making contact with the bulb. Put the bulb back in, plug your refrigerator back in. Does the bulb light?

    4.) Now we have narrowed the problem down to the light switch. The light switch is normally mounted on the inside wall. It may also be part of the top door hinge assembly (Push pin). If it is in a bottom freezer it is located on the inside top liner in the middle. These switched have pop in retaining clips. With a small flat head screw drive or a peeling knife gradually pry the switch out. You will see either two or three connectors. Remove the connectors noting how the wire leads are attached, The wire leads are short. Be carful not to let they fall down into the liner wall. Lets check the switch, if you have a multi-meter, set your meter to the lowest Ohms. With one meter lead on one switch contact and the other meter lead on the other switch contact, you should get a reading of '0' Ohms. Anything else then the switch is bad.
    Oh, you do not have a multi-meter, rest assured if you check the above you have a contact switch problem. Get the model number of your unit. Usually located on the fresh food section wall. Call you local appliance parts supplier and get a new switch.

    If you have a push pin switch in the top door hinge, there are either 1 or 2 screws to be removed to remove the hinge cover access the switch.

    Samsung has magnetic contact switches. In the door gasket, as with all door gaskets there is a flexible magnet strip. This strip makes contact at the top of the refrigerator front frame. In this case the magnet door gasket strip may be broken and had slipped out of position. In the case you must replace the door gasket. You can physically feel this magnet strip.

    Replace door switch


    My name is Peter. I am a retired field service refrigeration technician.

    Before you change you door light switch. Lets check it out. First, if you have changed the light bulb, did you use a refrigeration light bulb. These bulbs sometimes are available in your local food market. If you used a household light bulb it eventually will fail. The household bulb is not designed for cold temperatures.

    All appliances require specific light bulbs designed to the application such as, refrigerators, freezers, dishwashers, clothes washers and dryers. Of course they are more expensive $8.00-$10.00.

    Ok, lets assume you have the correct appliance light bulb in your refrigerator. With the door open push on the door light switch. If the light comes on your door switch.

    All door switches are basically the same they are plastic two contacts, except for one that is a 3 contact switch. The third contact controls the ice dispenser. This switch is on the left side of the freezer wall (Liner).

    Ok, lets change a door light switch. Unplug your refrigerator. With a small flat head screw driver (or butter knife) wedge behind the plastic switch frame. Pop it out. Be careful, do not pull it out too far. You will see the two connectors. It may be difficult to remove the connector, so wedge them with a flat head screw driver (Or butter knife). Do not pull on the wires, just the metal connector.

    Ok, with your particular model the contact switch is on the top of your unit. There are two screws holding the hinge cover plate. These screws are either Phillips head or hex head. Either 1/4" or 5/16" hex head. Remove the hinge top cover. You have one on each side. There is a connector. With a small screw driver, wedge into the connector to release it. The rest is yours.

    We have a 2001 Ford Windstar and noticed today that none of the rear lights are working. Is there a fuse that may have blown for this to happen all at once or something else?

    There is brake switch that is located on the brake oedal bracket, just to the right of the steering column mount. Youl need to remove the left side under dash panel to get to the switch and connector.
    If the brake lights are inoperative, check the fuse.
    If fuse is Ok, check the voltage at the light bulb socket when switch is not presed and when is presed. If there is no voltage back to the light bulb replace brake switch.

    Rear brake lights inoperative . The upper brake light on trunk deck works, but the lower lights in the main assemblies are inoperative.

    That is a little strange, but could be just bulbs have blown. Switch must be ok if high mount works, so check bulbs first. Unless there is a separate fuse you could check that too.

    Saturn Turn Signal / Dome Light Issues

    The interior lamps system consists of 2 main features. Illuminated entry and a battery saver feature that will turn the interior lights off after 20 minutes if they are left On with all doors closed and the ignition Off. The body control module (BCM) controls both of these functions. Battery power is supplied by the BCM through CKT 1732 to the following lamps:
    • The dome lamp
    • The map lamps
    • The rear reading lamps
    • The rear dome lamp
    • The cargo lamp
    • The glove compartment lamp
    • The courtesy lamps
    • The sunshade lamps
    The BCM also controls the ground circuit side of the dome lamp and reading lamps for illuminated entry. The dome lamp and reading lamp will remain on for 20 seconds after the ignition key is removed and the last door is closed. In addition, if the vehicle is equipped with remote keyless entry (RKE), the dome and reading lamps will turn On and stay on for 20 seconds after an UNLOCK signal is received from the keyless entry transmitter.
    The reading lamps, dome lamp and map lamps can be turned On at any time by moving the appropriate switch to the On position.
    The rear dome lamp is fed battery voltage through CKT 1732 from the BCM, through the liftgate ajar switch, and is grounded through CKT 650 to the rear ground splice pack. The rear dome lamp will turn on when the liftgate is opened. The cargo lamp is fed battery voltage through CKT 1732 from the BCM, through CKT 744 and grounded through the decklid ajar switch.
    The courtesy lamps are fed battery power through CKT 1732 and are grounded through CKT 745-- left front, CKT 747--left rear, CKT 748--right rear, CKT 746--right front. These circuits will ground through the door jamb switches. The courtesy lamp will be illuminated when the affected door is opened. For example, when the right rear door is opened, the right rear door courtesy lamp will turn on.

    Not a fuse problem , if the BCM had blown fuse other thing's wouldn't be working as well . . Probably wiring or BCM . Using factory diagnostic,s instead of guessing as to what the problem is , is the proper way .

    Interior Lamps Diagnosis
    Important: Before proceeding with these diagnostics, check for DTCs. If DTCs are present, complete the associated diagnostics. If the condition still exists, return to this chart.
    All of the interior lamps are inoperative when any door is opened.
    Chart 1
    The dome lamp is inoperative in the ON position, but OK in the door position. The map lamps operate normally.
    The dome lamp switch is faulty. Replace the dome lamp switch.
    The dome lamp is inoperative in the DOOR position, but is OK in the ON position.
    Chart 2
    The dome lamp is inoperative in any position and both reading lamps are inoperative.
    Disconnect the dome lamp connector (BLK 3-way).
    Check for voltage at terminal "C" CKT 1732 ORN wire.
    If OK, the dome/map lamp is faulty. If no voltage is present, there is an OPEN in CKT 1732.
    Either the right or the left sunshade mirror lamp is inoperative.
    Chart 3
    Either the right or the left rear reading lamp is inoperative in the ON or the DOOR position.
    Chart 4
    The rear reading lamp is inoperative in the ON or the DOOR position.
    Chart 5
    Battery rundown protection is shorted to ground - B1482.
    The left rear reading lamp is inoperative in the ON or the DOOR position.
