6.2. TROUBLE-SHOOTING
Operational
failure Cause Procedure to be followed
The furnace
does not heat 1. Thermocouple.
The heating regulator has a
security that turns off the heat in
case of thermocouple breakage. In
this case the indicator stays off.
- Check the continuity of the thermocouple
with an Ohmmeter or a sound test.
- If you do not have such device, a visual
examination will inform you on the level of
wear (the wire should not be cut).
- Replace the thermocouple: see chapter 6.3.
2. Heating regulator
Heating indicator stays lit
continuously, but there is not
temperature rise.
- Remove the back panel and check resistance
at the muffle (35 ohms) with a multimeter.
- If the resistor is damage: replace it (see
chapter 6.4).
The furnace
heats
continuously 1. Of that happens just after
changing the thermocouple.
It is because the positive or
negative wires have been
reversed.
- Connect correctly the thermocouple’s
polarity:
+ : green wire / - : white wire
NOTE: the negative wire (white) is slightly
magnetic (check with a magnet).
2. It can also come from a
defective heating regulator. - Replace the heating regulator: contact the
after-sale service.
In all cases, if the failure persists, contact the after-sale service.
