Conveyor Oven not heating, checked voltages, 237.7 High Voltage, But only 22.4 volts on Low Voltage, recommend to replace Transformer and relay, had 22.4 at gas valve but would not pull in, transformer is weak, contact said to replace both transformers in upper and lower unit. 9/05/19 Top oven, Replaced old Fenway ignition module with the new updated Fenway module. Cleaned ignitor, checked at set gas pressure to 4.0 in WC. Checked both cooling fans, okay. Unit still comes up with error Open and 909F error. Temp control module face is melted and probe is no good. Kyle said replace both ASAP. Bottom over, replaced obsolete Honeywell ignition module with the new Fenwal updated module, running now and seems okay. Cleaned ignitor, checked gas pressure and set at 4.0 in WC. Checked the 24 volt, seems okay, left the transformer with manager. Per Kyle. Will return with new Temperature module and probe to replace.
