    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

Johnson Control A419 malfunction?

Hello Everyone,

So I've had this Johnson control A419 thermostat with night time drop controlling the heat to a RHP (Pro Products 35watt) in my chondro cage for the past year with no issues. However, recently I was playing around with my setup and was unplugging it often and switching heating elements to and from it. During this same time I noticed that my RHP was no longer working and seemed to have short circuited. So I threw the RHP away and switched the Johnson control out to regulate the temp of my kane heat matt in my Sav's cage instead. Well this morning i noticed that the Johnson control was at a steady 83 degrees, eventhough i had it setup for about 95 degrees. So i plugged the kane matt to the wall outlet and to my suprise I got no power. I monitor my enclosures very closely and it was working just fine up until last night. Last night i noticed the thermostat read 93 degrees, but when i touched the matt it wasn't hot, so i increased the temp a few degrees and this morning it was not working at all.:angry:

Has anyone experienced something similiar? I have another kane matt, but I'm reluctant to connect any of my other heating elements to this thermostat, because I have lost two heating elements within a week of each using the Johnson control. Could it be possible that the thermostat is short circuiting my heating elements? Should i rewire the thermostat and is there any way to tell if this is causing damage to my heating elements?

Any feedback would be appreciated

Thanks,
 
Oh i forgot to mention that i had the probe attached directly to the kane matt, which could also be the cause of the problem.
