Hi, I have a Intertherm E2EB heater and I keep blowing 240/24 Volt transformers. I put a new one in (old one was blown, no 24V out, primary was open), and in fan only mode the transformer holds up, but when I switch to heat mode via the t-stat, the heater comes on for about 3 seconds then blows the transformer. Funny thing is, the inline 3 amp fuse on the low voltage did not blow as you would expect from a high load on the 24V side.
Could this be from a possi
ble shorted t-stat wire, or a sequencer or relay pulling too much load? I vhecked all the wires going to the components in the control area and they are all in great shape.
