broken old heater

I have a old heater such as displayed. If it's not working, is there anyway that I fix it? When turning the knob, nothing happens.

Thanks.

Generally speaking it is easier and safer to replace rather than repair something like this. However, depending upon the problem it may be repairable.

But before going there, have you verified that power is getting to the heater? Is there an external thermostat involved? Does the thermostat work?

I cannot find the power supply. It seems to be just connected to the wall.

By "thermostat", are you refering to the turning knob? It does not work.

The knob is actually a combination switch and thermostat. If you can verify that power is getting to the unit, the switch is probably ad. Although you might be able to find a replacement, it's probably easier (and maybe cheaper) just to replace the entire heater.

What do you mean, "I cannot find the power supply?"

The unit runs on alternating current, probably 240 volts. A circuit breaker (or fuses) in your panel protect the circuit that feeds the heater. Have you verified that the circuit breaker is turned on or that the fuses are not blown?

Either the unit has it's own thermostat built in to the know, or there is an thermostat on the wall. The thermostat cycles the unit on and off to maintain the desired temperature. It looks like the unit has itís own thermostat, but it could also have one on the wall.

The electrical wires enter the unit from one end or the other, underneath the cover panel.

You need to verify that the circuit breaker is on or the fuses are not blown.

You need to find the external thermostat (if there is one) and verify that it works.

You need to check for power entering the unit on the electrical wires.

Be careful. Electricity can and does kill people.

If you still have no clue what I am talking about or feel uncomfortable making tests on live power, then call an electrician.

This is all I needed to read to determine that tvboy may be in over his head, and I hope he realizes 240 volts can be doubly as dangerous as 120 volts.

the other question it came up in my mind is this place is your home or apartment ??

if apartment ; one waring here most state[s] laws dont let the tentent to work on electrical system and have to call the landlord to repair or replace this heater

the 240 volt heater is not a fun task and have good chance to get electric shock if not carefull

I cannot find the power supply. It seems to be just connected to the wall
now this did raise the red flag here if you dont know where is the breaker box or fuse box located the best bet is call the landlord [ if in apt. ] or get electrician to come out and do the repair or replace the heater

please think twice for safety sake here

Merci, Marc
