In the cold winter, many families need heating equipment, such as heaters or air conditioners. If the heater switch is broken when using the heater, what should be done, how to check the cause, and what kind of maintenance methods are available, these are all we need to understand and clear.
(1) The heating tube of the heater does not light up, and the fan does not turn. reason:
1. The circuit is disconnected or the contact is poor.
2. The switch or socket is in poor contact.
3. The fuse is blown.
4. The heating wire is blown.
Overhaul:
1. Overhaul and reinstall.
2. Repair or replace switches and sockets.
3. Reconnect after finding out the reason.
4. Replace the heating wire or replace the entire heating tube.
(2) The heat of the heater fluctuates up and down, the reasons are:
1. The socket or switch is loose.
2. The fuse is in poor contact.
3. The heating wire connector is ignited and then disconnected.
Overhaul:
1. Tighten and reinforce.
2. Adjust the conductive metal sheets at both ends of the fuse box to make good contact.
3. Re-tighten the screws.
(3) The heater does not heat up after being energized. Reasons:
1. The power plug is not in good contact with the socket.
2. The power switch is in poor contact or damaged.
3. The heating wire is broken.
Overhaul:
1. Re-insert the plug. If the copper clip in the socket is badly deformed, use small pliers to correct it so that the clip can clamp the plug.
2. The switch of the electric heating mattress is usually a miniature bedside switch. When repairing, the switch box is removed, and the movable and fixed copper sheets are wiped with metallographic sandpaper to remove oxides or dirt; if the pressure of the movable contact sheet is insufficient, It can be bent a little with small pliers to make it have good contact when pressing the stator; if it is seriously damaged, it should be replaced.
