bensioux 0 Report post Posted February 19 Hi, i've got a problem with Frontier 500. It's turning off my main fuse (which i have on the wall in my shop - only Frontier is connected to this fuse). When i am trying to turn it on it start to work after 5th, 6th time and after that everything is ok. When i'm coming to work fuse is off but Frontier is look like it's somwhere in the middle of warming up. Could it be some heater or sensor doing that or rather the problem is with my fuse or electric installation in my shop (it's only 5 years old). Thank You Bartek Quote Share this post Link to post Share on other sites
Minilab service 249 Report post Posted February 19 In most cases it cause heater. Disconnect heaters and compare resistance. If one of them has different resistance it will be faulty. All heaters are the same - 200V 200W/240V 288W. If resistance similar can be that heater has current leakage to ground. Try disconnect all heaters ( unplug heater connectors ) and turn on minilab. Of course chemicals will not heat, but you see your wall breaker will be disconnected, or not. If wall breaker will not be disconnected then one by one connect heaters and allow to preheat tank. Look, which heater disconnect wall breaker. If when connected one heater all heaters will not disconnect wall breaker then might be that wall breaker is bad and disconnects, when it shouldn't be.
