How can'I ck the control panel i have truble w/defroster not workin.. the defroste relay click but won't stays on.
hoshizaki freeser model #FH2-AAC
Need more info.
Generally, Hoshi freezers have 2 sensors and a limit in the evap compartment. One sensor is for conditioned space temp, one is for evap temp, and limit if for the heater.
Basically, while in defrost, the controller monitors the evap temp, and when it reaches approx. 70 degrees, the defrost should terminate. The limit kills power to the heater should it get too hot prior to defrost termination. I would first check to see if heater is getting power, if not, check the limit as they go bad frequently. If it is getting power but the defrost termination is happening too early, I would replace the probes first as it is the cheaper route and even if the controller is bad, I would not replace it without doing the probes too. The safety in the controller is usually set for if the unit does not terminate defrost on temp, it will terminate on time, usually 1 hour set at factory specs. Let me know if you need any further help.
