I have an 1998 Intertherm heater with a blower that has E2EB015HA on the blower. The elements get red hot but the blower doesn't come on. So I ordered a sequencer for a E2EB015HA which was listed Intertherm 621678 - Aftermarket Replacement 15 KW Heat Sequencer Relay. It is the wrong part, it mounts upside down from my old one, the 3 section part is on bottom instead of the top. The numbers on the 3 section sequencer I bought are KSD301C 24V C-031, H1-110 C1-110 , 1604. The numbers on the 2 section part are the same numbers.

My old sequencer has TOD, H24V, 12522, 308850, L9837. and H24V , 12520 308495, L9837.

I just found a sequencer #621678R that has a lot of the same numbers as the old one, and mounts the correct way:
TOD, H24 V, 12522, 308850, A1340, and H24V, 12520, 308495, A 1340.

Can someone please tell me if I am on the right track here. Thanks
