Performed silver club heater maintenance. Filter was clogged and causing limit switches on elements to trip. Replace filter. Test capacitor and motor amp draw. Amp draw in range. Test sequencers, relays in limits. All are in working order. Amp draw to 1 side is slightly elevated but in working order. Breaker could be in a little better condition. Spoke to customer about it. Customer will replace breaker if needed. Unit is putting out 120f heat. Heater is working properly at this time.
