Intertherm Model MMHB-070ABHR-06

Unit wont start after a few minutes of cycling and the Control Module Status Indicator flashes 3 times continuously.

Indicator panel says that three flashes means:

Failed ignition attempt, a gas valve error, or a false flame sensed during the warmup period

Any suggestions as to possible repair attempt?

Thank you

Hi,

Control Module: On call for heat:

L1 and L2 = 120vac

IND and L2 = 120vac

After approx. 1 minute :

HSI and HSIG = 120vac

PSI and C = 24vac

PSO and C = 24vac

GV and C = 24vac



Thanks,
Robert
