When the FQ4000 calls for heat, a latch circuit and heat contactor have to close and stay closed. If that does not happen, the vat does not heat and the controller logs E19. Frymaster's troubleshooting table lists a gas valve left off, a failed controller, a failed transformer, a failed contactor or an open high-limit thermostat as causes. Frymaster commercial appliance display · also shown as HEATING FAILURE, HEATING FAILURE – XXX F What to do when E19 shows on the commercial appliance ### Kind of code Controls and power The controller itself is reporting trouble, or the supply behind it is: a display with dead segments, a keypad that stopped responding after steam or degreaser got behind it, relays that stick, stored recipes or cycles that vanished overnight, a blown control fuse, or one leg of a three-phase feed missing so half the heat or the pump is gone. A full power cycle at the breaker, done as the manual describes, clears a passing glitch; a code that returns, a scorched smell or any sign of moisture behind the panel means the breaker stays off, and that is a visit. ### Usually leads to Commercial controls and board repair Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone. ### Make Frymaster A Frymaster fryer is serviced cold: the visit waits until the oil has come down and the vat has been drained by the crew. ### Source Frymaster FilterQuick FQG30U easyTouch gas fryer manual with FQ4000 controller (error log codes, section 5.6) FQ4000 easyTouch touchscreen controller on FilterQuick fryers (FQG30U and related FilterQuick gas and electric models). The same troubleshooting row covers E19 and E28 together. ## Before you book, in this order. Each step comes from Frymaster's own guidance for E19 on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Check that the gas valve on the fryer is in the on position and that the gas quick-disconnect behind the fryer is fully seated, without loosening any fitting. 02 Power-cycle the controller once, pausing roughly sixty seconds between off and on; Frymaster notes this message can show at startup while air clears the gas lines. 03 If HEATING FAILURE returns with gas confirmed on, shut the vat down and have the contactor, transformer and high-limit circuit tested on a visit. ### Still there? It usually turns into [commercial controls and board repair](https://commercialappliancerepair.center/services/commercial-controls-and-board-repair/). Book with the code and the model number. ### What not to do E19 is about the heat circuit not engaging; E28 is the gas burner failing to light and the ignition module locking out. A slow climb to temperature with no error is a recovery problem (E44), not E19. ## What you may notice with it. The commercial appliance problems E19 tends to arrive with.

Check that the gas valve on the fryer is in the on position and that the gas quick-disconnect behind the fryer is fully seated, without loosening any fitting. If it comes back, it needs a visit. ### Why does my Frymaster show HEATING FAILURE right after a filter cycle? Air can get into the gas lines at startup, and Frymaster says the message is normal in that case. If it keeps coming back once the fryer has been running, the latch circuit needs testing. ### Is E19 a gas problem or an electrical one on a Frymaster? It can be either. A closed gas valve shows up the same way as a failed contactor or transformer, which is why the gas valve is checked first. ### Will a Frymaster with E19 heat at all? Normally not on the affected vat, because the circuit that turns heat on is not holding. The other vat of a split or battery may still work. --- **[Read on the site: Frymaster E19: the heat control latch did not hold on the FQ4000](https://commercialappliancerepair.center/error-codes/frymaster-e19/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
