Re: BEKO DRVS 73 W HEATING ELEMENTS CUT OUT
Theres a low temperature switch on the front, make sure its not selected, e/g lit, if it was selected dryer runs only on 1/2 heat.
N.T.C controls heating during drying with sensor under door switching off when degree of dryness is achieved.
Problems with poor heating could be attributed to blocked fan, blocked ducting or filters, or even on the outlet grill on outside of wall where vented air exhausts.
P.C.B could be at fault but this should be last resort to change.
