Faults

c) clean
the valve according to chapter “
Cleaning solenoid valves
”.
If the fault still remains, then:
–
Switch off the power (pos. 0).
–
Disconnect plug ( 2 ) from the coil ( 4 ) and measure the resistance. 3.3 K for 220VAC
valves is a normal value.

The heating elements are used up. See
chapter “
Bad combustion
”.
–
The furnace is faulty. See Chapters
“
No combustion
”
,
“
Resistance furnace
”
,
“
Resistance furnace doesn’t reach full temperature”
,
“
The resistance furnace is too
cold or too hot
”
and
“
Resistance furnace takes too long to warm up
”.

The heating elements are used up, and the required temperature can only hardly be
reached so that there are no reserves of power, to properly regulate the temperature at a
stable level. See chapter
“
Resistance furnace doesn’t reach full temperature
”. To
confirm this fault, set the temperature to a much lower value. If the temperature cannot
reach the new higher level, it is obvious that the unstable temperature was at maximum
level of temperature the heaters can reach.
–
The temperature control board TH 43/44 is faulty. Replace the TH 43/44 board and adjust
according to chapter
“
Resistance furnace
”.
–
The thermocouple is faul
ty. See chapter “
Thermocouple testing
”.
