Brand: Mavrik Model Number: 54-1077 Main Symptom: Delayed ignition on first startup of the day What happens & when: What happens & when: Installed a new Mavrik 54-1077 LP gas valve a month ago on gas range. Lately I’ve noticed that after sitting overnight, the first call for heat takes a few extra seconds before the burner lights. After that it runs normally the rest of the day. Gas pressure checks out and the pilot is stable. Before I start chasing other components. Has anyone seen similar behavior? For reference, here’s the exact valve I’m working with 541077 - Gas Valve 3/8" | Allpoints
Error Code (if any): None

A delayed ignition on the first call for heat after sitting overnight, followed by normal operation for the rest of the day, is not typically caused by the gas valve itself if the valve is opening and operating normally once the system has been used.
A few things I would check before suspecting the new Mavrik 54-1077 LP gas valve:
Pilot flame size and position – Even if the pilot appears stable, it may not be fully engulfing the thermocouple/thermopile or providing enough flame carryover to quickly ignite the main burner after a long idle period.
Pilot orifice partially restricted – A small amount of debris can reduce pilot output enough to cause delayed ignition, especially when the appliance has been sitting.
Main burner crossover ports – Rust, grease, or debris in the lighting ports near the pilot can slow flame propagation to the burner.
LP regulator performance – Static pressure may check good, but a regulator can occasionally be slow to respond after an extended idle period. Checking dynamic pressure during ignition can help rule this out.
Air in the gas line – Uncommon if the issue just started after a month of normal operation, but worth considering if any gas work was recently performed.
I have seen similar symptoms where the gas valve was suspected, but the root cause ended up being a weak pilot flame or partially obstructed burner carryover ports. Since the burner lights normally after the first cycle and continues to operate correctly throughout the day, I would lean toward an ignition or flame-transfer issue before condemning the valve.
A couple of questions:
Does the delay occur only on the oven burner, or on surface burners as well?
Approximately how many seconds does it take from the thermostat calling for heat until the burner actually ignites?
Is there any noticeable gas odor during the delay period?
Thanks for the detailed reply. The delay is only on oven burner. Once it lights it cycles normally for the rest of the day without any issues. The delay is probably around 3 to 5 seconds on the first call for heat and there’s no noticeable gas odor during that time. I’ll take a closer look at the pilot flame and the burner crossover ports since I haven’t inspected those yet. That’s a good point about flame carryover. I was focusing on the valve because the issue seemed to start not long after it was installed but I’m definitely not ruling out ignition related problem.
