I had a working HM that controlled a SSR within my electric smoker. The SSR was mounted inside the smoker and I discovered things were too hot there when the HM shutdown (LCD off) and I discovered that the blower control wires driving the SSR shorted together. I replaced the shorted wires, replaced the SSR (and mounted it in a location outside the smoker. Today I did a quick test to see how things were going to work. I found that the HM appeared to operate and wasn't shutting down and the fan control graph looked like the fan output was variable. But, the SSR controlling the heating element never appeared to kick off when the fan control output went to 0%. Would shorting the fan output wires have damaged some internal parts on the HM? Or should I look for some other variables like the new SSR possibly being bad? Here's a graph (I shut it off at the peak after detecting the overrun):
